In the following function defined by an equation in the form y = a x squared + b x + c, identify the values of a, b, and c. y = negative 2 x squared a. a = negative 2, b = 0, c = 0 b. a = negative 2, b = negative 2, c = negative 2 c. a = 0, b = negative 2, c = 0 d. a = 0, b = 0, c = negative 2

step-by-step explanation:

just plug in each number for x and see which ones work and don't

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.
