Me answer this question so i can move on. give a short explaination so i know what to do on future problems

The graph plots x-values on the horizontal axis. It is the horizontal line labeled "x" at the right side of the graph. Values near zero (small values) are near the y-axis, which is the vertical line labeled "y" at the top. Negative x-values are on the left side of the y-axis.

To answer the question, find small x-values (near the y-axis on the left side) and find the corresponding points on the plot of F(x), the blue curve. You will see they are large negative y-values (well below the x-axis). This observation guides you to select ...
  B. F(x) is a very large negative number.


What to do on future problems: understand what the problem statement is telling you about where to look on the graph, then read the graph.

Y = 7(x + 2)(x + 4)
First, multiply the x factors out
y = 7(x² + 6x + 8)
Now, multiply by 7
y = 7x² + 42x + 56
