Math Problem Statement

Write the standard form of the quadratic function that has the indicated vertex and passes through the given point. Vertex: (-6, 2), Point: (-4, 3).

Solution

The problem on the screen asks to "Write the standard form of the quadratic function that has the indicated vertex and passes through the given point."

Information given:

  1. Vertex of the parabola: (6,2)(-6, 2)
  2. Point on the parabola: (4,3)(-4, 3)

Solution Steps:

  1. Vertex Form of a Quadratic Function: The vertex form of a quadratic function is: f(x)=a(xh)2+kf(x) = a(x - h)^2 + k where (h,k)(h, k) is the vertex of the parabola.

  2. Substitute Vertex Values: Since the vertex is (6,2)(-6, 2), we substitute h=6h = -6 and k=2k = 2: f(x)=a(x+6)2+2f(x) = a(x + 6)^2 + 2

  3. Use the Point (4,3)(-4, 3) to Solve for aa: Substitute x=4x = -4 and f(x)=3f(x) = 3: 3=a(4+6)2+23 = a(-4 + 6)^2 + 2 Simplify inside the parentheses: 3=a(2)2+23 = a(2)^2 + 2 3=4a+23 = 4a + 2 Subtract 2 from both sides: 1=4a1 = 4a Divide by 4: a=14a = \frac{1}{4}

  4. Write the Final Equation: Substitute a=14a = \frac{1}{4} back into the equation: f(x)=14(x+6)2+2f(x) = \frac{1}{4}(x + 6)^2 + 2

This is the standard form of the quadratic function with the given vertex and passing through the given point.

Further Questions:

  1. What is the process for converting from vertex form to standard form of a quadratic function?
  2. How do you find the axis of symmetry from the vertex form of a quadratic function?
  3. How would the equation change if the given point was different?
  4. What are other methods for finding the value of aa in a quadratic function?
  5. How can you verify the solution by graphing?

Tip:

Always double-check your calculations, especially when substituting points to solve for parameters.
