Question

f(x) =2x - 33 for x=9???

Answer 1

What are the instructions?

Answer 2

evaluate each function for the given value of x, and write the input x and output f(x) as an ordered pair @Teddyiswatshecallsme

Answer 3

ooh i ahven't gotten to functions yet, sorry. ;-; I CAN'T HELP... Ifeel so useles.s.

Answer 4

its okay thank you!

Answer 5

we have a function \[\large f(x) = 2x - 33\]

and we are told to figure out what that function will equal...when x = 9

So to find that out...all we do is replace every 'x' we see in the original equation...with 9

\[\large f(9) = 2(9) - 33\]
\[\large f(9) = 18 - 33\]
\[\large f(9) = ?\]

Answer 6

f(9) = -15

Answer 7

Perfect!

Answer 8

it says write the input and output values as an ordered pair?

Answer 9

oh and could you help me with one more please

Answer 10

Okay, so the input is the 'x' value....and the output is what the function equals with that input value..

So what did we input? we did x = 9
what did that output? it outputted y = -15

So the ordered pair would be (x,y) = (9 , -15)

Answer 11

ohhhh okay okay awesome

Answer 12

And of course I'll help you out with another :P

Answer 13

yayyy

Answer 14

f(x) = -2x +1/3 for x = -5

Answer 15

Alright so same thing here (gonna make you do it this time :P)

we have

\[\large f(x) = -2x + \frac{1}{3}\]

and they want to know what that equals if you make 'x' = -5

Answer 16

my ordered pair i got was (-5, 11/3)

Answer 17

its actually \[-2x + 1\div3\]

Answer 18

not just 1/3 its all over the 3

Answer 19

Oh its the full thing

\[\large \frac{-2x + 1}{3}\]

Then yes your ordered pair is correct!

Answer 20

sorry can you check just one more for me and then i should be good ahah

Answer 21

lol of course :)

Answer 22

f(x) - 2/9x for -9/2 for x =9 and i got (9, -9) for my ordered pair
