Pic attached- if x^4 * x^a = x^16 and (x^2)^b = x^8, what is the product of a and b?

c

Step-by-step explanation:

x^4 * x^(4) = x^16

(x^2)^(4)=x^8

^(4)*^(4)=16

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.
