(p+g)(x) funtions: g(x) = 2x²+5 p(x) = x² - 2x

Answer
7) f(x + 2) = 3x + 2
9) h(5x - 3) = 17 - 15x
Explanation
Since, the others have an answer, I'll solve number 7 and number 9; the ones without an answer,
7) f(x + 2)
f(x) = 3x - 4
f(x + 2) = 3 (x + 2) - 4
= 3x + 6 - 4
= 3x + 2
9) h(5x - 3)
h(x) = 8 - 3x
h (5x - 3) = 8 - 3 (5x - 3)
= 8 - 15x + 9
= 17 - 15x
Hope this Helps!!!
