Work Shown:
Now plug in x = 5
---------------------
Alternative approach:
h(x) = x-7
h(5) = 5-7
h(5) = -2
So this means
g(h(5)) = g(-2)
and
g(x) = x^2
g(-2) = (-2)^2
g(-2) = 4
Therefore making

Answer:
y = 9x^2 -8x +9
Step-by-step explanation:
The given equation has derivative ...
y' = 2ax +b
The requirements on slope give rise to two equations:
2a(1) +b = 10
2a(-1) +b = -26
Adding these equations together gives ...
2b = -16 ⇒ b = -8
Then we have ...
2a -8 = 10
a = (10 +8)/2 = 9
__
The given point lets us find the constant term c.
y = 9x^2 -8x +c
c = y -(9x -8)x = 29 -(9(2) -8)(2) = 29 -20 = 9
The equation of the parabola is ...
y = 9x^2 -8x +9
