Which expression is equivalent to x2 - 9?
a (x – 3)
b (x – 3)(x– 3)
c (x − 3)(x + 3)
b (x + 3)(x + 3)

C. (x-3)(x+3)

Step-by-step explanation: Since both terms are perfect squares, factor using the difference of squares formula a^2-b^2=(a+b)(a-b) where a=x and  b=3.

Hope this helps you out! ☺

C

Step-by-step explanation:

x*x= x^2

-3*(+3)=-9

2x-9

take it another

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.
