Describe the graph of the exponential function below.

 $f\left(x\right)=3\left(.75\right)^x$  

• The graph represents exponential growth, with a  y-intercept at .75; as the x-values decrease the graph approaches 0, but never reaches it.

• The graph represents exponential decay, with a  y-intercept at 3; as the x-values decrease, the graph approaches 0, but never reaches it.

• The graph represents exponential decay, with a  y-intercept at .75; as the x-values increase the graph approaches 3, but never reaches it.

The graph of f(x) = 2^x is moved 3 units down and 2 units to the right. Which function models the new graph?

• f(x) = 2^{x + 2} – 3

• f(x) = 2^{x + 2} + 3

• f(x) = 2^{x – 2} – 3

• f(x) = 2^{x – 2} + 3
