Which of the following functions satisfies these two characteristics: f(0) = 0, f(2) = π
A. f(x) = -2 sec(x)
B. f(x) = 7sin(x/4 - 1/29)
C. f(x) = π cos(πx)
D. f(x) = 2π cos(x - π/2)

Hey stay safe during hard times

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.
