F(x) = 3(6 - x) , what is the value of f(- 8)

The answer is 42 ansd to find the answer plug in -8 for x.

Step-by-step explanation:

f(-8) =3(6-(-8))

f(-8)=3(6+8)

f(-8)=3(14)

f(-8)=42

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
