The two linear functions ƒ(x) and g(x) are shown below. ƒ(x) = x + 3

Which of the following is true?

A. he rate of change of the function g(x) is –2.

B. The rate of change of ƒ(x) is times the rate of change of g(x).

C. The rate of change of ƒ(x) is greater than the rate of change of g(x).

D. The product of the rate of changes of ƒ(x) and g(x) is -6.

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

positive
