Graphical Behavior: Example 2

Graphical Behavior

Find the y-intercept of the function.

$frac1$

Step 1. Simplify the function completely.

$frac1$

$frac2$

$frac3$

$frac4$

When x = 0, the denominator is 1, therefore the function is defined.

Step 2. Substitute x = 0 into your simplified equation and solve.

$frac5$

$frac6$

$frac7$

y-intercept: (0, 3)
