Math Problem Statement
Solution
The given question asks to graph the function by using transformations starting from the parent function . Let's walk through the steps of how this transformation works:
Transformations Breakdown:
-
Start with the parent function:
.
This is a standard parabola that opens upwards, with the vertex at . -
Horizontal Shift:
The function has a horizontal shift.- shifts the graph 5 units to the left (because the shift is opposite to the sign inside the parentheses).
-
Vertical Shift:
The term moves the graph 4 units down.- So, the new vertex will be at .
-
No Reflection or Stretch/Compression:
- The coefficient inside the squared term is 1, so the shape (width) of the parabola remains the same as the parent function.
- There is no reflection (as there is no negative sign).
Summary of Transformations:
- Shift left by 5 units: .
- Shift down by 4 units: .
- No stretching/compression or reflection.
Thus, the vertex of the transformed parabola will be at (-5, -4), and it will maintain the same "U" shape as the original .
Graphing Instructions:
- Plot the vertex at .
- Since the graph is not stretched or compressed, follow the usual pattern:
- From the vertex, move 1 unit right/left and 1 unit up to get additional points.
- Then move 2 units right/left and 4 units up (since ).
- Draw a smooth curve passing through these points.
Would you like me to create an image of this graph, or do you need more clarifications?

Tip: When dealing with transformations, always check the sign inside the parentheses for horizontal shifts—it behaves opposite to intuition.
