Please give step by step answer

- 4x² - 3

Step-by-step explanation:

g(x) = - 4x + 2

g(x²) = - 4x² + 2

h(x) = x² - 5

h(x²) = (x²)² - 5 = - 5

Then

g(x²) + h(x²)

= - 4x² + 2 + - 5

= - 4x² - 3

or

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
