Question

What are the domain and range of the function f(x)=-3(x-5)2 +4?

Answer 1

D.

Explanation:

Domain: (-infinity, +infinity)

Range: (-infinity, 4)

Answer 2

D=(-infinity, +infinity)

R=(-infinity, 4]

Explanation:

I think that 2 is an exponent so you function is f(x)=-3(x-5)^2+4

So if this is the case this is a parabola open down when a vertex of (5,4).

Visualize or draw a rough picture of that because that is all you need to answer this question.

The domain for a parabola function is always all real numbers (do notice I said parabola function).

The range for this parabola is (-infinity, 4] since open down and the highest point has y value 4.
