Find the value of (64/25)^-1/2 Give your answer as fraction in its simplest form.

Step-by-step explanation:

has a negative, fractional indice; this negative sign in this context means to make the base fraction a reciprocal (flip it!):

The denominator is the value by which we should root, then the numerator is the power the fraction should be raised to: [root and then raise]

This fraction then becomes:

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.
