Math Problem Statement

Find the vertex of the quadratic function: f(x) = -3(x - 2)^2 - 4.

Solution

To find the vertex of the quadratic function f(x)=3(x2)24f(x) = -3(x - 2)^2 - 4, we can use the vertex form of a quadratic equation, which is:

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

Here:

  • a=3a = -3 (the coefficient of the squared term),
  • h=2h = 2 (the value inside the parentheses),
  • k=4k = -4 (the constant outside the squared term).

The vertex of a quadratic function in vertex form is given by the point (h,k)(h, k). Therefore, the vertex of this quadratic is:

(2,4)(2, -4)
