Question

Find the vertex and x-intercepts using a calculator.

A. Vertex: (h, k), x-intercepts: (a, 0)
B. Vertex: (a, 0), x-intercepts: (h, k)
C. Vertex: (h, k), x-intercepts: (h, 0)
D. Vertex: (h, 0), x-intercepts: (a, k)

Answer 1

The correct answer is A. Vertex: (h, k), x-intercepts: (a, 0). To find the vertex and x-intercepts of a quadratic function using a calculator, follow these steps.

Step-by-step explanation:

The correct answer is A. Vertex: (h, k), x-intercepts: (a, 0).

To find the vertex and x-intercepts of a quadratic function using a calculator, you can use the graphing feature. Follow these steps:

1. Enter the quadratic function into the calculator.
2. Graph the function.
3. Find the vertex by looking for the highest or lowest point on the graph. The coordinates of the vertex will be in the form (h, k).
4. Find the x-intercepts by looking for the points where the graph intersects the x-axis. The coordinates of the x-intercepts will be in the form (a, 0).

Using a calculator can make it easier and more accurate to find the vertex and x-intercepts of a quadratic function.
