Math Problem Statement
Graph the equation y = (x + 2)^2 + 5 by transforming the given graph of the parent function.
Solution
The equation given is:
This is a transformed version of the parent function , which is a standard parabola opening upwards. Here’s how each part of the equation affects the graph:
- Horizontal Shift: The inside the square indicates a horizontal shift. Since it’s , the graph shifts 2 units to the left.
- Vertical Shift: The outside the square moves the graph 5 units up.
As a result, the vertex of the parabola, which is normally at for , is now at .
The transformed graph should show a parabola opening upwards with its vertex at .
Would you like a further breakdown of these transformations or have any specific questions?
Here are some related questions:
- What is the effect of a negative sign in front of the squared term, such as in ?
- How would the graph change if we had instead?
- What happens if we add a coefficient to the squared term, like ?
- How does the vertex form of a parabola help in quickly identifying transformations?
- Can we rewrite in standard form?
Tip: When graphing transformations, start with the vertex shift and then apply other transformations like stretching or reflecting.
