Part a: if (72)x = 1, what is the value of x? explain your answer. part b: if (70)x = 1, what are the possible values of x? explain your answer. ! : •d

It's hard to tell if you are using x as an exponent or if you are multiplying by it. Below are the answers for both cases.

Multiplying by x

Part a - the answer would be 1/72.

Part b - the answer would be 1/70.

In order to find the correct number to solve the equation, you would need to divide both sides by the number being multiplied by x. Once you do that, you will have the above fractions on one side and x on the other, giving you the value of x.

x as an exponent

The answers for both part a and b would be 0.

With exponents, any number raised to the 0th power is equal to 1. This is the rule for the power of 0. So, these problems are solved fairly quickly using this rule.

if you have 100 bucks, and you want to buy a candy bar, even if you have one at home, if you choose not to buy it, you save.

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! : )
