Domain =

Range =

#### Explanation:

Since this is a 2nd degree quadratic function, it implies its graph is a parabola and in this case with axis of symmetry at x=0 and y-intercept of 0, with the arms going up.

Therefore the domain is all real values for x, ie

The range is all y values greater than or equal to zero, ie
