What is the range of y = (x - 5)^2 – 1?

1.  The graph is a parabola.

2. The parabola opens up, because there's no negative number in front of .

3. The vertext is (5,-1), because of the vertex form.

This means that that -1 will be the least y-value used on the graph and the garph will open up from there.

The range is (-1, infinity) or { y | y > -1 }.

d. 8

step-by-step explanation:

the given radical expression is:

we can rewrite this as:

we express as square numbers to get;

the exponents will now cancel out to give.

the correct answer is d

use distributive property on all like terms and change your signs if you have a double negative or if you have positive/negative
