The graph of the function b is shown below. find b(1). a.) -1 b.) 1 c.) 2 in advance!

Step 1) Locate 1 on the x axis. The x axis is the horizontal axis number line

Step 2) Draw a vertical line through 1 on the x axis. Extend this vertical line as far as you can go up and down the page.

Step 3) The vertical line crosses one of the given points, namely the point (1,2). The y coordinate of this point is what we want. This is the output of the B(x) function when x = 1. If x = 1, then B(x) = 2. Put another way B(1) = 2
