Describe the graph of a function g by observing the graph of the base function f. A: g(x) = -1/2f(x)
B: g(x) = 2f(-x) g(x)
C: g(x) = 1/2f(-x)
D: g(x) = f(-1/2x)

the first option i believe

step-by-step explanation:

yx = 36

step-by-step explanation:

cos f = opposite side/ hypotenuse

cos f = yw / yx

we know cos f = 4/9 and yw =16

4/9 = 16/yx

multiply each side by yx

4/9 yx = 16/ yx * yx

4/9 yx = 16

multiply each side by 9/4

9/4 * 4/9 yx = 16 *9/4

yx = 36
