Mrs. Johnson informed her students that their exam will have at most 25 questions. x>25
x>=25
x<25
x<=25

it would be x>25 because it would either be up to 25 questions or less

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.

chad should not have included the values (1, 2) and (3, 6) because that would mean he only had half a healing card.
