3. The function below is defined by two equations. The equation in the first row gives the output for negative numbers in the domain. The equation in the second row gives the output for non-negative numbers in the domain. Find the indicated function values.

f(x) = 6x+8 if x < 0

5x+9 if > 0

a. f(-2)

b. f(0)

c . f(8)

d. f(-100)+f(100)

9. Find a. (f + g)(x)

b. (f + g)(9).

f(x) = 4² - x + 3, g(x) = x + 4

10. Let f(x) = x² - 4 x and g(x) = 1 - x

Find (fg)(2)
