Which equation, when graphed, has x-intercepts at (8,0) and (-2, 0) and a y-intercept at (0, -48)?
f(x) = -3(x - 3)(x + 2)
f(x) = -3(x + 8)(x - 2)
f(x) = 3(x - 3)(x + 2)
f(x) = 3(x + 3)(x - 2)

None of the above.

Step-by-step explanation:

The simple way to solve the question is by substituting the given points in all the options. It is given that f(8) = 0, f(-2) = 0, and f(0) = -48.

It is easier to use the last option so substituting f(0) in all the options:

A) f(0) = -3(0-3)(0+2) = -3 * -3 * 2 = 18.

B) f(0) = -3(0+8)(0-2) = -3 * 8 * -2 = 48.

C) f(0) = 3(0-3)(0+2) = 3 * -3 * 2 = -18.

D) f(0) = 3(0+3)(0-2) = 3 * 3 * -2 = -18.

It can be clearly seen that none of the options satisfy f(0) = -48. So the answer is none of the above!!!

both equations and proportions are better.
