Rewrite the radical expression as an expression with a rational exponent.

pls help

Step-by-step explanation:

In order to solve this question we need to understand the following.

=

(Notice that the numerator of the fraction is the power of the x that is being squared)

If you need proof here it is.....

=

x = x

Now that we got that out of the way we can rewrite as........

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.
