Math Problem Statement

graph each function and identify the vertex and axis of symmetry

g (x) = (x-2)^2 - 3

Solution

The function g(x)=(x2)23g(x) = (x - 2)^2 - 3 is a quadratic function in vertex form, which is given as:

g(x)=a(xh)2+kg(x) = a(x - h)^2 + k

Here, hh and kk represent the vertex of the parabola, and the axis of symmetry is the vertical line x=hx = h.

For the function g(x)=(x2)23g(x) = (x - 2)^2 - 3:

  • h=2h = 2
  • k=3k = -3

So, the vertex is (2,3)(2, -3).

Axis of symmetry:

The axis of symmetry is the vertical line that passes through the vertex, so it is:

x=2x = 2

Graph:

The parabola opens upwards since the coefficient of (x2)2(x - 2)^2 is positive (the coefficient is 1), and the vertex is at (2,3)(2, -3). The general shape will resemble a U-shaped curve with its lowest point at the vertex.

Would you like me to graph it for you?


Here are some additional questions to deepen understanding:

  1. How does changing the value of hh affect the graph of the function?
  2. What happens if the coefficient in front of (x2)2(x - 2)^2 changes to a negative number?
  3. How can you find the y-intercept of the function g(x)g(x)?
  4. How would the graph look if the function were g(x)=(x+2)23g(x) = (x + 2)^2 - 3?
  5. How does the value of kk influence the graph's vertical position?

Tip: The vertex form of a quadratic function makes it easy to identify the vertex and axis of symmetry, simplifying graphing tasks!
