Rewrite the function by completing the square f(x)=x ^2 +4x−60

Hi there! :)

f(x) = x² + 4x - 60

Rewrite:

0 = x² + 4x - 60

Complete the square by creating a perfect square trinomial. Make sure to add the third term to both sides:

0 + 4 = (x² + 4x + 4) - 60

Rewrite the trinomial as a square binomial:

4 = (x + 2)² - 60

Subtract 4 from both sides:

0 = (x +2)² - 64

Rewrite:

f(x) = (x + 2)² - 64

2 for the first box and -64 for the second one.

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
