The answer is D. the y-intercept will be (0,25), the slopes of the line segments will 80 and 120, and the range will be [25,1145].

the answer is d. 75%

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.

you can't solve x because it is 2 linear equation and you only have one equation

b
