Look at the graph. On a coordinate plane, a line with negative slope goes through points (0, 2) and (4, 0).

To find the rate of change of the function, Kevin did the following:

StartFraction 0 minus (negative 1) Over 2 minus 2.5 EndFraction = StartFraction 1 Over negative 0.5 EndFraction = negative 2.

What was Kevin’s mistake?
He incorrectly chose (–1, 2.5) as a point on the graph.
He incorrectly chose (0, 2) as a point on the graph.
He mixed up the numerator and the denominator of the fraction.
He subtracted –1 from 0 when he should have added –1 to 0.

the answer is c i did the test again and got it right

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! : )
