Which of the following best describes the expression 3x + 2y + 8z?

The sum of three products; there are three terms

Step-by-step explanation:

Which of the following best describes the expression 3x + 2y + 8z?

The product of three sums; there are three terms

The sum of three products; there are three terms

The product of three sums; there are six terms

The sum of three products; there are six terms.

As you can see from the options, there is only one that is correct, since the terms are adding up, each term is 3x, 2y, and 8z, these are the three terms that we can find in the expression, and since they are products of a multiplication, they are the sum of three products, and there are only three terms, remember that the word product in math means the result of a multiplication, since 3 is multiplying x 2 is multiplying y and 8 is multiplying z we have three multiplications, or 3 products, and we are adding them up, so the correct option would be The sum of three products; there are three terms.

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! : )
