The first thing we are going to do to find (g°f)(3), is find (g°f)(x). To do that, we are going to evaluate g(x) at f(x):
(g°f)(x)=

Now, we can evaluate (g°f) at 3:




We can conclude that the correct answer is
c. 49
I think it is c, I could be wrong though
Answer:
Only one extreme value of f(x) is possible.
Step-by-step explanation:
We are given the quadratic function of independent variable x which is f(x) = x² - 7x - 6 ......(1)
Now. the condition for extreme values of f(x) is 
Hence, differentiating both sides of equation (1) with respect to x, we get
= 0
⇒ x = 3.5.
So there is only one value of x for which f(x) has extreme value which is x = 3.5.
Therefore, only one extreme value of the given function is possible. (Answer)
-129/13
Find x then subtract 9

Don’t forget to carry the one to the left
6+4= 10 carry the one to the left.
8+3+1 = 8+4 =12
