12 1/2 (2 1/2+3 1/2) (2 1/2 - 31/2)

-975 is the answer to your problem.

12 * 0.5 = 6

6(2.5+3.5) = 36

36(2.5-31/2) = -975

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
