Math Problem Statement

Sketch the graph of the quadratic function h(x) = (x - 3)^2 + 2 and compare it with the graph of y = x^2.

Solution

To solve this problem, let's analyze the given quadratic function:

Given Function:

h(x)=(x3)2+2h(x) = (x - 3)^2 + 2

Comparison Function:

y=x2y = x^2

Step 1: Understand the General Form

The function h(x)=(x3)2+2h(x) = (x - 3)^2 + 2 is a transformation of the standard quadratic function y=x2y = x^2. This is in the vertex form of a parabola: y=(xh)2+ky = (x - h)^2 + k where (h,k)(h, k) is the vertex of the parabola.

  • In this case, the vertex is at (3,2)(3, 2).
  • The graph of y=x2y = x^2 has a vertex at (0,0)(0, 0), which is the origin.

Step 2: Transformations

The transformations that have been applied to y=x2y = x^2 are:

  • Horizontal shift: The graph is shifted 3 units to the right, because of (x3)(x - 3).
  • Vertical shift: The graph is shifted 2 units up, because of the +2+2.

Step 3: Graph the Function

  1. The graph of h(x)=(x3)2+2h(x) = (x - 3)^2 + 2 will have the same "U" shape as y=x2y = x^2 but will be:
    • Shifted to the right by 3 units.
    • Shifted up by 2 units.

Step 4: Comparison with y=x2y = x^2

  • Shape: Both graphs are parabolas with the same shape since the coefficient of x2x^2 is the same (no stretching or compressing).
  • Position: h(x)h(x) is translated 3 units to the right and 2 units up compared to y=x2y = x^2.

Would you like me to generate a visual graph for this?


Let me know if you have any questions or need further details. Here are some related questions you might explore:

  1. How would the graph change if we replaced +2+2 with 2-2?
  2. What if the function was h(x)=2(x3)2+2h(x) = 2(x-3)^2 + 2? How would this affect the shape?
  3. What is the axis of symmetry for both functions?
  4. How do you find the y-intercept for h(x)h(x)?
  5. Can you find the x-intercepts (roots) of the function h(x)h(x)?

Tip: Understanding transformations in vertex form helps visualize changes without plotting the full graph!
