The answer should be D. If you plug it in,

-11 x 2 = -22 24 x 3 = 72

72 -22 = 50

4 x -11 = -44 2 x 24 = 48

48 -44 = 4

"The function is decreasing":

This means the slope of the function will be negative at the given point. Anywhere the line is going down, from left to right, is decreasing. This eliminates choices A and C.

"The function is concave down":

This means the curve of the function will be open down (think of an upside down u). This eliminates choice E.

"f(x)>0":

This is anywhere the curve is above the x axis. This eliminates choice D.

The answer is Choice B) x=2.
