Two more than four times a number is -10 ?

-3

Step-by-step explanation:

4n + 2 = -10

      -2    -2 =

4n=-12

4n/4 and -12/4

n= -3

Double-check:

4(-3) + 2 = -10

-12 + 2 = -10

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.
