\]
Describe how the graph of the function can be obtained from the graph of a basic exponential function.
Start with the graph of $y=2^{x}$. Shift it left 5 units and then shift it down 2 units.
Use the graphing tool to graph the equation.
Solution
Solution Steps
Step 1: Identify the Basic Exponential Function
The basic exponential function is \( y = 2^x \).
Step 2: Apply Horizontal Shift
Shift the graph of \( y = 2^x \) to the left by 5 units. This results in the function \( y = 2^{(x+5)} \).
Step 3: Apply Vertical Shift
Shift the graph of \( y = 2^{(x+5)} \) down by 2 units. This results in the final function \( y = 2^{(x+5)} - 2 \).
Final Answer
The graph of the function \( f(x) = 2^{x+5} - 2 \) can be obtained by shifting the graph of \( y = 2^x \) left by 5 units and then down by 2 units.
