Describe the graph of the function. y = the graph is an absolute value function with vertex (7, –4). the graph is an absolute value function with vertex (4, –7). the graph is an absolute value function with vertex (–4, 7). the graph is an absolute value function with vertex (–4, –7).

i'm sorry i don't know

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

16 would be your answer
