The answer is x bc when you decreasing the interval f(x) it will equal (-2)
Slope: Take two points from the graph, and do y-y, over x-x.
for ex. (1,2) and (2,4) do 4-2 over 2-1. your slope is 2/1= 2
y-intercept: find the one point on the graph that is exactly on the y-axis.
for ex. (4,0)= your y-intercept is 4
(2x +3)(2x-3)= 0
x= -3/2 x = 3/2
Answer: the slope is 3/4.
y=mx+b and m is always the slope.
