The table represents data measuring the sound pressure level for noises with various sound pressures.
If the sound pressure level is calculated based on the
sound pressure, which regression equation models the
data?
y= = 80(x) 1.01
y = 80(1.01)
y = 93.62logx + 19.81
y = 93.62 + 19.81logx

free points lol thanks for them

Step-by-step explanation:

answer: b

step-by-step explanation:

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! : )
