Write the phrase as an expression. Then evaluate when y=20. the quotient of 40 and the difference of a number y and 16

Expression:

When y=20, the value of the expression is

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
