Randi had surgery on her knee. Right after the surgery
she could bend her knee only 30° from a horizontal
position. After six weeks of physical therapy, she can
bend it 108°. How many more degrees can she move
her knee after therapy? Explain.
Doesn’t the answer have to be in a degree

Well, we know that she could only bend her knee 30 degrees from the start.

And after six weeks of therapy, she can bend it 108 degrees.

So that means: 108 - 30 = 78 degrees more.

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! : )
