15 POINTS PLLLSSS HELP
Which statement BEST describes this quadratic function?
A) decreasing when x < 0
B) decreasing when x < –1
C) decreasing when x > –1
D) decreasing when x > 1 and x < –3

C) decreasing when x > –1

Step-by-step explanation:

To determine whether a function is increasing or decreasing, or whether it increases or decreases in an interval, you must look at the function or the interval from left to right.

Start at the left and move to the right. You see that the function (the y-coordinate of each point) is increasing from an v value of negative infinity till x = -1. At x = -1 the function reaches a maximum point. Now start at x = -1 and, moving to the right, the value of the function (the y-coordinate of each point) decreases.

The correct answer is C) decreasing when x > –1

the answer is c
