functions in algebra

Question

consider the function y=x^20

what is the range of the function

Answer 1

Hi Ashley, the range of the function is the valid values for y.

 

x can take on any value from -∞ to +∞.

 

Since the power of x is even, y must be positive.

 

The range of y is values from 0 to +∞.
