Observe the graph:
\Find a point such that the line crosses the x-axis.
\The line crosses the x-axis at (3, 0).
\Since the line crosses the x-axis at (3, 0), the x-intercept is 3.

Find the y-intercept. \ \
\Find a point such that the line crosses the y-axis.
\The line crosses y-axis at (0, 4).
\Since the line crosses the y-axis at (0, 4), the y-intercept is 4.

The zero of the function is the x-intercept of the graph. So, Zero = 3. \ \
\![\"\"](\"http://www.mathskey.com/userfiles/image/steps_images/solution.JPG\")
The x-intercept is 3.
\The y-intercept is 4.
\Zero of the function is 3.
