Question

Can someone help me with this math homework please!

Answer 1

Answer:  Choice A

Explanation:

Choice A has the f(x) values going down on the interval -1 < x < 1 only.

Choice B appears to be decreasing over its entire domain, so we can rule this out (since we want -1 < x < 1 to be the only decreasing interval).

Choice C's table isn't decreasing when -1 < x < 1 since y = -3 increases to y = 0 (from x = -1 to x = 0). So we can rule it out.

A similar situation happens with choice D as well, so we can rule this out. The function isn't decreasing when we go from f(-1) to f(0).
