Math Problem Statement

In the xy-plane, the function h is graphed on the interval 0 ≤ x ≤ 10. The point (3, -2) is on the graph of y = h(x). Which of the following points is on the graph of y = 2h(x) - 1?

Solution

We are given that the function h(x)h(x) is graphed, and the point (3,2)(3, -2) is on the graph of y=h(x)y = h(x). Now, we need to find which of the points is on the graph of y=2h(x)1y = 2h(x) - 1.

Step-by-step process:

  1. Original function information: We know that h(3)=2h(3) = -2 because the point (3,2)(3, -2) is on the graph of y=h(x)y = h(x).

  2. Transformation of the function: The new function is y=2h(x)1y = 2h(x) - 1. To find the corresponding point for x=3x = 3 in the new function:

    • Start with h(3)=2h(3) = -2.
    • Substitute h(3)h(3) into the new function: y=2h(3)1=2(2)1=41=5.y = 2h(3) - 1 = 2(-2) - 1 = -4 - 1 = -5.
    • Thus, the point (3,5)(3, -5) is on the graph of the transformed function y=2h(x)1y = 2h(x) - 1.

Conclusion:

The correct point that lies on the graph of y=2h(x)1y = 2h(x) - 1 is (3,5)(3, -5), which corresponds to option B.
