Question

Algebra 2 Connexus students!!!! I WILL DO ANYTHING... PLEASE HELP

Answer 1

In your lab, a substance's temperature has been observed to follow the function T(x)=(x+5)^3, The turning point of the graph is where the substance changes from a liquid to a solid. Explain to your fellow scientists how to find the turning point of this function, USING COMPLETE SENTENCES.

Answer 2

Well first of all, you need to factor that equation into a polynomial. So factor:
(x+5)^3
(x+5)(x+5)(x+5)
x^3+15x^2+75x+125

Answer 3

But notice in the part of factoring where it says (x+5)(x+5)(x+5), there is x+5 three times.

Answer 4

There for there is only one repeating zero of the polynomial, and that zero is "encoded" in x+5. So by setting x+5=0, you turn out with -5 as the zero.

Answer 5

i have to write it complete sentences.. btw Thank you for helping me!

Answer 6

So this polynomial turns at -5

Answer 7

@evan97 do you mind helping me some more?

Answer 8

Sure

Answer 9

two students in your class, tucker and karly are disputing a function. tucker says that for the function, between x=-3 and x=3, the average rate of change is 0. Karly says that for the function, between x=-3 and x=3, the graph goes up through a turning point, and then back down. Explain how tucker and karly can both be correct, USING COMPLETE SENTENCES

Answer 10

Graphing the function?

Answer 11

Would that be acceptable?

Answer 12

I have to use sentences

Answer 13

They can graph the function using paper or a calculator to determine where the turning point lies.

Answer 14

can you expand more on how they do that? :)

Answer 15

@evan97

Answer 16

but if thats all.... can we move to another question? :)

Answer 17

Yeah sure. Explaining how to graph polynomials is a long process so you might just want to leave it at that. Next question?

Answer 18

you are having a conference call with the CEO of a paper company. You have interpreted the number of trees cut down versus profit as the function P(x)=-x^4+x^3+7x^@-x. describe to the CEO what the graph looks like. Use COMPLETE SENTENCES and focus on the end behaviors of the graph AND WHERE THE COMPANY WILL BREAK EVEN.

Answer 19

The part in caps(the second part of the question) is what i need help with
