Sarah is 8 years old. she has an older brother whose age is represented by the expression 3x + 2, where x
represents sarah’s age.
how old is her brother?

26

Step-by-step explanation:

Since x = 8

3 * 8 = 24

24 + 2 = 26

Therefore, Sarah’s brother should be 26. Forgive me if I’m faulty, I’m simply an Algebra1 student.

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! : )
