Write an equation of the parabola in vertex form that passes through (13,8) and has vertex (3,2).

Step-by-step explanation:

Vertex: (3,2)

Point: (13,8)

The equation form is

h = 3

k = 2

y = 8

x = 13

Plug in the values into the form..

Simplify and solve for a..

Plug a into the equation..

Hope this helped you!

c-4 is the final answer! : )

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.
