A) What is the y-coordinate of every point
on the x-axis?

Step-by-step explanation:

y-coordinate of every point on x-axis is 0 [zero]

0.

Step-by-step explanation:

The x axis can also be described by the equation y = 0.

We would write the point where x = 2 on the x-axis as (2, 0).

3.76%

step-by-step explanation:

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.
