How do you do this? simple and concise explanation+ answer,

Step-by-step explanation:

-4 is an open spot. It belongs to neither f(-4) = - 1 nor f(-6) = -2 All the open spots have that property. The answer should be = -1. f(-4) is the only point that gives f(x) = - 1.

Step-by-step explanation:

At x=-4, you traverse vertically, and will hit two points that touch the function somewhere.

At y=-1, we have a horizontal line extending from x=-4 to -2, which means that y=-1 applies to x=-4 to x=-2.

At y=-2, we have a horizontal line extending from x=-6 to -4, which means that y=-1 applies to x=-6 to x=-4.

This potentially means that there are two y-values at x=-4.  The convention is that a hollow circle (at y=-1) cancels the solution at that point, which means that at x=-4, the only valid value for y is at y=-2.

Therefore the value of y at x=-4 is -2, so (-4,-2) is a solution.

$3,200 x 7.25% = $3,200 x .0725 = $232 interest monthly

$232 monthly x 12 annual = $2, 784
