The function g(x) is shown on the table. Suppose f(x) = 4x − 2. When comparing the functions, which describes the x-value when g(x) becomes greater than f(x)?
x g(x)
1 1
2 4
3 9
4 16
5 25
A) The x-value is between 1 and 2
B) The x-value is between 2 and 3
C) The x-value is between 3 and 4
D) The x-value is between 4 and 5

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.

table 3 represents a direct variation function. : )
