Lisa is flying from Bush Intercontinental Airport in Houston, TX to Newark International Airport in New Jersey with the wind. The trip is approximately 1415 miles. Lisa then flies from Newark International
Airport to Dallas-Fort Worth International Airport against the wind which is approximately 1372 miles
away. The wind speed is the same on both parts of her trip. Without the effect of wind, her airplane
travels at an average rate of 530 miles per hour for both trips. The total time Lisa spends in the air is
8.5 hours. What is the speed of the wind?

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! : )
