Martina is currently 14 years older than her cousin joey.

in 5 years she will be 3 times as old as joey. use this information to

answer the following questions.

a. if you let x represent joey’s current age, what expression can you use

to represent martina’s current age?

b. based on your answer to part a, what expression represents joey’s age

in 5 years? what expression represents martina’s age in 5 years?

c. what equation can you write based on the information given?

d. what is joey’s current age? what is martina’s current age?

answer: b. f(x) = (x + 2)^3 (x^2 - 7x + 3)^4

step-by-step explanation:

polynomials always have as many roots as their order. this is a 4th order polynomial- hence 4 roots!

complex roots of polynomials always come in pairs. the quadratic equation has the "+/-" in that will alwaysgenerate m+ni amd m-ni, so 7-2i must be a root of this polynomial equation.

the order of the numerator and denominator are both 2. so the horizontal asymptote is y=a2/b2 =7

verticle asymptotes are the forbidden x-values. f(x) becomes undefined at x=-3 because this value will cause a zero denominator.

a graph of r(x) will have vertical asymptotes at ±1 because these values will make the denominator zero. so the domain of the function cannot include ±1.

you 're wlecome! : )
