Step-by-step explanation:
If you graph this, you start at 1500 on the y-axis. Every time the x-axis increases by 1, the y-axis increases by 200. This forms a straight line, making it exponential since it increases by a constat amount.
Answer:
the opposite
Step-by-step explanation:
Answer:
(x-3)(x+3)(x+2)
Step-by-step explanation:
x^3 + 2x^2 - 9x -18
= x^2(x+2) - 9(x+2)
= (x^2 - 9) (x+2)
= (x+3)(x-3)(x+2)
