@undeadknight26 @mathmath333

OpenStudy (anonymous):

help :(

undeadknight26 (undeadknight26):

All of them need answered?

OpenStudy (michele_laino):

question 4) hwre we have to evaluate this quantities: \[\Large f\left( {10} \right) = ...?\;f\left( 3 \right) = ...?\]

OpenStudy (michele_laino):

oops..these*

OpenStudy (anonymous):

(10)(3)

OpenStudy (anonymous):

?

OpenStudy (anonymous):

30?

OpenStudy (michele_laino):

you have to use your function: \[\Large f\left( x \right) = 2 \times {3^x}\]

OpenStudy (anonymous):

ok, wait

OpenStudy (anonymous):

idk ;/

OpenStudy (michele_laino):

you have to replace x with 3 and x with 10

OpenStudy (anonymous):

oh

OpenStudy (anonymous):

f (3) = 2 x 3^10

OpenStudy (anonymous):

@Michele_Laino

OpenStudy (anonymous):

are you there @Michele_Laino ?

OpenStudy (anonymous):

@Michele_Laino

OpenStudy (michele_laino):

hint: \[\Large \begin{gathered} f\left( 3 \right) = 2 \times {3^3} = 2 \times 27 = ...? \hfill \\ f\left( {10} \right) = 2 \times {3^{10}} = ...? \hfill \\ \end{gathered} \]

OpenStudy (anonymous):

wait

OpenStudy (michele_laino):

f(10) is a very big number, so please use a calculator

OpenStudy (anonymous):

i use wolfram i copy and paste: 0?

OpenStudy (michele_laino):

yes!

OpenStudy (anonymous):

so whats nexts?

OpenStudy (michele_laino):

now we have to compute the same quantities, using this function: \[\Large g\left( x \right) = 3 \times {4^x}\]

OpenStudy (anonymous):

where its the formula, or its the same formula?

OpenStudy (michele_laino):

namely we have to evaluate these quantities: \[\Large \begin{gathered} g\left( 2 \right) = 3 \times {4^2} = 3 \times 16 = ...? \hfill \\ g\left( {10} \right) = 3 \times {4^{10}} = ...? \hfill \\ \end{gathered} \]

OpenStudy (anonymous):

g(2) = 3x4^2 = 3x16 = 48? g(10) = 3x4^10 = 0?

OpenStudy (anonymous):

im right?

OpenStudy (michele_laino):

48 is right! the second is a very big number g(10)=3*1048576=...?

OpenStudy (michele_laino):

since 4^10=1,048,576

OpenStudy (anonymous):

what i need to do now?

OpenStudy (michele_laino):

next ste: we have to write the function of Carter

OpenStudy (anonymous):

how?

OpenStudy (michele_laino):

we have to read the text of your problem

OpenStudy (michele_laino):

I think that the function used by Carter is: \[\Large h\left( x \right) = 10 \times {2^x}\] am I right?

OpenStudy (anonymous):

yes i think so

OpenStudy (michele_laino):

ok! now we have to compute these quantities: \[\Large \begin{gathered} h\left( 2 \right) = 10 \times {2^2} = 10 \times 4 = ... \hfill \\ h\left( {10} \right) = 10 \times {2^{10}} = 10 \times 1024 = ... \hfill \\ \end{gathered} \]

OpenStudy (anonymous):

carter: 10(2)^x?

OpenStudy (anonymous):

ok

OpenStudy (michele_laino):

sorry I have made an error, we have to compute g(3) and h(3) not g(2) and h(2)

OpenStudy (michele_laino):

\[\Large \begin{gathered} g\left( 3 \right) = 3 \times {4^3} = 3 \times 64 = ...? \hfill \\ g\left( {10} \right) = 3 \times {4^{10}} = ...? \hfill \\ \end{gathered} \] \[\Large \begin{gathered} h\left( 3 \right) = 10 \times {2^3} = 10 \times 8 = ... \hfill \\ h\left( {10} \right) = 10 \times {2^{10}} = 10 \times 1024 = ... \hfill \\ \end{gathered} \]

OpenStudy (anonymous):

h(2)=10x2^2=10x4= 40? h(10)=10x2^10x1024= 10485760?

OpenStudy (anonymous):

im not sure about the last one, but im right?

OpenStudy (michele_laino):

we have: \[\Large \begin{gathered} h\left( 3 \right) = 10 \times {2^3} = 10 \times 8 = 80 \hfill \\ h\left( {10} \right) = 10 \times {2^{10}} = 10 \times 1024 = 10240 \hfill \\ \end{gathered} \]

OpenStudy (anonymous):

so...

OpenStudy (michele_laino):

so, we have completed the question 4)

OpenStudy (anonymous):

yea, but whats nexts? i did something wrong?

OpenStudy (michele_laino):

I think you have done right!

OpenStudy (michele_laino):

now we have to compare the graph of the new function of Amber, with the graph of the old function of the same Amber

OpenStudy (michele_laino):

the new function is: \[\Large {g_2}\left( x \right) = 3 \times {4^x} + 45\] whereas the old function is: \[\Large {g_1}\left( x \right) = 3 \times {4^x}\]

OpenStudy (anonymous):

i need to solve that? right?

OpenStudy (michele_laino):

I think that we have to draw both those graphs

OpenStudy (anonymous):

im not good doing graph ;(

OpenStudy (michele_laino):

it is simple, the graph of the old function is like below: |dw:1437499913652:dw|
