The table shows the percentage of total athletes at a school that play certain sports. each athlete only plays one sport. twenty athletes play baseball. how many athletes are there at the school? (sport/ baseball % = ? // football % = 30% // other % = 45%)

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.
