1.
a. fog(x) = (x + 5) + 2 = x + 7
b. gof(x) = (x + 2) + 5 = x + 7

2.
a. gof(x) = 2(x - 2) - 2 = 2x - 4
b. fog(x) = (2x + 3) - 2 = 2x + 1

3.
a. fog(x) = (2x² - 6) - 2 = 2x² - 8
b. gof(x) = 2(x - 2)² - 6 = 2(x² - 4x + 2) - 6 = 2x² - 8x - 2

4.
a. gof(x) = 3(x² - 4x + 2) - 7 = 3x² - 12x - 1
b. fog(x) = (3x - 7)² - 4(3x - 7) + 2 = (9x² - 42x + 49) - 12x + 28 + 2 = 9x² - 54x + 79
c. 14
d. 439
