Question

Graph the function and identify the domain and range? y=-0.25x^2

Answer 1

The domain is: `{x|x " is " RR}` or (-oo, oo)

The range `{x|x <=0}` or `(-oo, 0]`

Explanation:

the graph is a parabola that is inverted because a is negative, it is also compressed by a factor of `0.25`

The domain is: `{x|x " is " RR}` or `(-oo, oo)`

The range `{x|x <=0}` or `(-oo, 0]`

graph{-0.25x^2 [-10.17, 12.33, -9.585, 1.665]}
