Math Problem Statement
Solution
The problem is asking for the transformations required to graph using the base function .
Let's break down the transformations:
-
Shift the graph horizontally to the left by 3 units:
- The term inside the square indicates a horizontal shift 3 units to the left.
-
Vertical reflection:
- The negative sign in front of the 2, , reflects the graph about the x-axis.
-
Vertical stretch by a factor of 2:
- The factor of 2 in front of stretches the graph vertically by a factor of 2.
-
Shift the graph vertically upward by 1 unit:
- The constant at the end shifts the graph up by 1 unit.
Given this breakdown, the correct transformations are:
- A: Shift the graph 3 units to the left.
- B: Shift the graph 1 unit up (this option is correct but labeled incorrectly in the image; "down" should be "up").
- E: Reflect the graph about the x-axis.
- F: Stretch the graph vertically by a factor of 2.

Here are 5 related questions for deeper understanding:
- What happens if the graph is shifted 3 units to the right instead of left?
- How does a horizontal stretch affect the graph of a quadratic function?
- What is the effect of a vertical compression on the graph of ?
- How would the graph change if the constant was instead of ?
- How does a horizontal reflection differ from a vertical reflection?
Tip: Always check the signs inside and outside the parentheses to determine whether a graph shifts left or right, and whether it stretches or compresses.

Formulas
Standard quadratic function f(x) = x^2
Transformation formula for shifts: g(x) = a(x - h)^2 + k
Theorems
Horizontal shifts: (x + 3) shifts the graph left by 3 units
Vertical shifts: +1 shifts the graph up by 1 unit
Reflection across the x-axis: the negative sign before the 2
Vertical stretch: multiplying by 2 stretches the graph vertically
