Math Problem Statement

f(x)=2(x-6)squared-7 what is the vertex

Solution

The given function is f(x)=2(x6)27f(x) = 2(x - 6)^2 - 7.

This is a quadratic function in vertex form, which is given by the equation:

f(x)=a(xh)2+kf(x) = a(x - h)^2 + k

In this form, the vertex is (h,k)(h, k), where:

  • hh is the x-coordinate of the vertex.
  • kk is the y-coordinate of the vertex.

By comparing f(x)=2(x6)27f(x) = 2(x - 6)^2 - 7 with the vertex form, we can see that:

  • h=6h = 6
  • k=7k = -7

Thus, the vertex of the function is (6,7)(6, -7).

Here are 5 related questions:

  1. How do you find the vertex of a quadratic function in standard form?
  2. What is the axis of symmetry for this function?
  3. How does the value of aa (in this case, 2) affect the shape of the parabola?
  4. What are the x- and y-intercepts of this quadratic function?
  5. How would you graph this quadratic function step-by-step?

Tip: The sign of aa in the vertex form determines if the parabola opens upward (positive aa) or downward (negative aa).
