the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

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

hence this is not a function.

step-by-step explanation:

75

step-by-step explanation:

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
