step-by-step explanation:

a'(12.5,11.25)

slope=(y1-y2)/(x1-x2)

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

the ordered pairs for the given function are of the form
