Which of the following describes the graph of y=x^2−144?

the graph has zeroes at x = -12 and x = -12 and it opens downward.

the graph has zeroes at x = 12 and x = -12 and it opens downward.

the graph has zeroes at x = 12 and x = 12 and it opens upward.

the graph has zeroes at x = 12 and x = -12 and it opens upward.

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.

where's the diagram?
