# High School Math : Graphing Exponential Functions

## Example Questions

### Example Question #1 : Graphing Exponential Functions

Find the -intercept(s) of .

This function does not cross the -axis.

Explanation:

To find the -intercept, set  in the equation and solve.

### Example Question #2 : Graphing Exponential Functions

Find the -intercept(s) of .

and

Explanation:

To find the -intercept(s) of , set the  value equal to zero and solve.

### Example Question #3 : Graphing Exponential Functions

Find the -intercept(s) of .

and

and

and

Explanation:

To find the -intercept(s) of , we need to set the numerator equal to zero and solve.

First, notice that  can be factored into . Now set that equal to zero: .

Since we have two sets in parentheses, there are two separate  values that can cause our equation to equal zero: one where  and one where .

Solve for each value:

and

.

Therefore there are two -interecpts:  and .

### Example Question #32 : Solving And Graphing Exponential Equations

Find the -intercept(s) of .

or

The function does not cross the -axis.
