Question

Graph the functions and identify the domain and range. y=-1.5x^2

Answer 1

The domain corresponds to all real number and range corresponds to any real number lesser than or equal to 0.

Explanation:

Polynomial functions are continuous. Second order polynomial have a vertix, which is an absolute maximum since coefficient is a negative number. The function is plotted as follows.

The domain corresponds to all real number and range corresponds to any real number lesser than or equal to 0.

Answer 2

You can give random values such as (1,2.5) (2,9) (-1,2.5) (-2,9) and it is a parabola. You'll see that the range is (-infinte, 0] and the domain is (-infinit, infinite). I hope that this is the answer that you were looking for and it has helped you.
