When trying to determine where to shade on the inequality below, why is it unhelpful to test the point (4,0)

It is not helpful to test this point because 4 is already a point in a square root parabola. This means that because it is a less than or EQUAL TO inequality then we already know this point will lie directly on the line and not be helpful in shading.

Step-by-step explanation:

took it on edge!

it costs $20 to interview each person for a survey. find the cost to obtain a +- 3% margin of error.

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! : )
