What is (-7)^-1 and how do you do it

-1/7

Step-by-step explanation:

First you need to understand negative exponents. Baisically it means 1/the number to the positive power. For this problem, it's

1/(-7)^1

-7^1=-7

(-7)^-1=-1/7

-1/7 or -0.1438...

Step-by-step explanation:

When there is a negative exponent the function under the exponent goes into the denominator making the equation negative one seventh -1/7

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! : )
