Math Problem Statement

Translate the graph of y = x^2 to the graph of y = (x + 4)^2 + 2.

Solution

The graph shown is of the function y=x2y = x^2, which is a standard parabola with its vertex at the origin (0,0)(0, 0).

The task is to translate this graph to match the equation y=(x+4)2+2y = (x + 4)^2 + 2. Here's how the transformation happens:

  • Horizontal Translation: The (x+4)(x + 4) term indicates a horizontal shift. Specifically, the graph is shifted 4 units to the left. In general, (x+h)2(x + h)^2 shifts the graph hh units horizontally, and since h=4h = -4, the graph moves left by 4 units.

  • Vertical Translation: The +2+2 outside the square indicates a vertical shift 2 units up. This means the graph moves upwards by 2 units.

So, the vertex of the new parabola will be at (4,2)(-4, 2) instead of (0,0)(0, 0).

Steps to graph the translation:

  1. Shift the entire graph of y=x2y = x^2 4 units to the left.
  2. Then, shift the graph 2 units upwards.

The result is a new parabola with vertex (4,2)(-4, 2), which opens upwards like the original graph of y=x2y = x^2, but is now translated.

Would you like more details on any of the steps, or do you have any questions?


Here are 5 related questions to think about:

  1. What is the effect of negative values outside the squared term, like y=x2y = -x^2?
  2. How would the graph change if the equation was y=(x+4)22y = (x + 4)^2 - 2?
  3. What does the general form y=a(xh)2+ky = a(x - h)^2 + k represent geometrically?
  4. How would the shape of the parabola change if the equation had a coefficient, like y=2(x+4)2+2y = 2(x + 4)^2 + 2?
  5. How does a vertical stretch or compression affect the vertex form of a parabola?

Tip: Always pay attention to signs inside and outside the squared term to understand horizontal and vertical shifts correctly!
