The inverse of f(x)=x^2 is also a function t/f

False

Step-by-step explanation:

The inverse of f(x) = x^2 is not a function, since the graph fails the vertical line test:  a vertical line drawn thru the graph intersects it in 2 places (except at (0,0) ).

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.

81 seats

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.
