Answer:

X

Step-by-step explanation:

To be a function, the line has to pass the vertical line test. This means that when a vertical line is passed through every x value, it will only cross the graphed line once.

To help: draw vertical lines through each graph.

In graph W: the line would pass through the top and bottom of the circle - not a function

In graph X: the line passes once through every area - a function

In graph Y: the line passes through the top curve as well as the bottom curve - not a function

In graph Z: the line passes through the curves multiple times - not a function

g(x) = 3x - 2

<u>Step 2: Find g(1)</u>

  1. Substitute in <em>x</em>:                    g(1) = 3(1) - 2
  2. Multiply:                               g(1) = 3 - 2
  3. Subtract:                              g(1) = 1

<u>Step 3: Find f[g(1)]</u>

  1. Substitute in g(1):                    f[g(1)] = 2(1) + 1
  2. Multiply:                                   f[g(1)] = 2 + 1
  3. Add:                                         f[g(1)] = 3
