The measure of ZEFH is twice the measure of ZGFH. What is the degree measure of ZGFH?

h is the x-coordinate of the vertex

step-by-step explanation:

we have

in this function

the point represent the vertex of the function

so

h is the x-coordinate of the vertex

k is the y-coordinate of the vertex

i believe that the answer is y+6=1/3(x+2)

i was unable to find the answer. good
