The town of bertsville increased from a population of 3562 people in 1970 to a population of 9765 in 2000. assume the growth was exponential
a. define an exponential function that models the towns population as a function of the number of years since 1970.
=
b. what is the annual percent change?
%
c. use your function to predict the town's population in 2019.
d. according to your function, in what year will the town's population reach 4 people?

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.
