HEL I HAVE 3 MORE MINUTES The graph of function f(x) intersects the x-axis at (-2, 0) and (4, 0). Which can be the function of the graph?
A. f(x)=x^2−2x−8
B. f(x)=x^2+2x−8
C. f(x)=x^2−4x−8
D. f(x)=x^2−2x+8

I'm pretty sure the answer is A. f(x) = x^2 - 2x - 8

Step-by-step explanation:

x + 107

step-by-step explanation:

let's say that the number he had before the mistake was x. then, he will have 107 dollars more than this, so the answer is x + 107.

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
