Transcript text: Graph the equation shown below by transforming the given function.
\[
y=\sqrt{x+1}-3
\]
Solution
Solution Steps
Step 1: Identify the Parent Function
The parent function for the given equation \( y = \sqrt{x + 1} - 3 \) is \( y = \sqrt{x} \).
Step 2: Horizontal Shift
The term \( x + 1 \) inside the square root indicates a horizontal shift. Specifically, \( x + 1 \) means the graph of \( y = \sqrt{x} \) is shifted 1 unit to the left.
Step 3: Vertical Shift
The term \( -3 \) outside the square root indicates a vertical shift. Specifically, \( -3 \) means the graph is shifted 3 units down.
Final Answer
The graph of the equation \( y = \sqrt{x + 1} - 3 \) is obtained by taking the graph of the parent function \( y = \sqrt{x} \), shifting it 1 unit to the left, and then shifting it 3 units down.
