The area, A, of a rectangle is 120x2 + 78x – 90, and the length, 1, of the rectangle is 12x + 15. Which of
the following gives the width, w, of the rectangle?
9x + 4

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.

many reason,
