13. mike says when you subtract (3.2 x 10") from (7.8 x 10') the answer is 4.6 x 10. what is wrong with his reasoning?
a) the correct answer is 7.48 x 10'. he should have adjusted the decimal and changed the exponent to 3 before
he subtracted.
b) he isn't wrong. that is the correct answer.
c) the correct answer is 7.48 x 10. he should have adjusted the decimal and changed the exponent to 4 before
he subtracted.
d) the correct answer is 11 x 10. when he changes the exponent to 3, he adds the coefficients.

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.
