Which of the following is an example of an identity? (1) x² + 2x+8 =(x + 2)(x+4)
(2) 2x(x – 3) +5x-15 = (2x+5)(x-3)
(3) x² +9=(x+3)
(4) x^3+8 =(x+2)(x^2+4)

step-by-step explanation:

10/60

step-by-step explanation:

if you divide 10 by 60 the answer is 0.166666 while if you divide or solve the other problems it equals 0.6

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.
