Solution Steps

Step 1: Identify the Vertex Form of a Parabola

The vertex form of a parabola is given by the equation:

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

In this form, the variables h h and k k represent specific characteristics of the parabola.

Step 2: Determine the Role of h h

In the vertex form, the variable h h represents the x x -coordinate of the vertex of the parabola. The vertex of the parabola is the point (h,k)(h, k).

Step 3: Analyze the Multiple-Choice Options

Let's analyze the given options to determine which one correctly describes the role of h h :

  • The value of x x at the x x -intercept: This is incorrect because h h is not related to the x x -intercept.
  • The value of x x at the vertex: This is correct because h h is the x x -coordinate of the vertex.
  • The value of y y at the y y -intercept: This is incorrect because h h is not related to the y y -intercept.
  • The value of y y at the vertex: This is incorrect because k k represents the y y -coordinate of the vertex.
  • The steepness of the slope: This is incorrect because the steepness is not determined by h h .

Final Answer

The correct answer is: The value of x at the vertex\boxed{\text{The value of } x \text{ at the vertex}}
