Practice: Graphing Exponential Functions

Worksheet
Graphing Exponential Functions

Use a calculator to determine the approximate value of each expression to the nearest hundredth.

1. 2^0.7

2. 3^-0.3

3. 4^1.1

4. 5^-4.1

Graph each function. State the y-axis intercept.

1. y = 3^x - 2

2. y = 2^{x + 1}

3. y = 3 · 2^x

4. y = (½)^x

Solve each equation.

9. 3^y = 3^{3y + 1}	10. 3^x = 9^{x + 1}
11. 8^{r - 1} = 16^3r	12. 9^3y = 27^{y + 1}
13. 2^{2n - 1} = 8^{n + 7}	14. 4^{x - 1} = 8^x
