Find x, if f(x) = 12 and Ax) = 3x. A.36 B.12 C.4 D.3

The answer is 4...

Explanation: this is a simple equation if you're trying to find X and f(x) = 12  but A(x) equals 3x your basically doing 3 times what equals 12 which in this case that would be 4 (well in any case it would be 4) I know this is confusing so hear me out (sorry)

f(x) = 12

A(x) = 3x  

3 x 4 = 12

x = 4

Like I said sorry if this makes you confused but the answer is 4 :)

brainliest? (even though I'm two weeks late)

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! : )

it would rotate about 180 degrees.
