Ihave 3 problems that i don't understand on my home work can some one
1) jack wants to buy a pair of trousers for $60 when he went to the store he found that the price was marked down by 20% how much do they cost now
2) sally buys a hand bag there was a discount of 30% if sally paid $20 what was the original price
3)kelley wants buy a magazine that it's $25 later the magazine was marked up an additional 20% what is the new price

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! : )
