Rewrite Exponential Function with Exponent Rules Mar 19, 8:33:17 AM
The value of a car that depreciates over time can be modeled by the function J(t)=27000(0.9)^{2t+2}
. Write an equivalent function of the form J(t)=ab^t. J(t)=ab
j(t)= ^t
.

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.
