Final answer:

The function h(x) = (0.5)x + 1 has a y-intercept of 1. Therefore correct option is A

Step-by-step explanation:

The function h(x) = (0.5)x + 1 has a y-intercept of 1.

To find the y-intercept of a function, we set x = 0 and solve for y. In this case, when x = 0, the function becomes h(0) = (0.5)(0) + 1 = 1. Therefore, the y-intercept is 1.

On the other hand, the other functions listed do not have a y-intercept of 1. For example:

  • h(x) = 5(2)x has a y-intercept of 0.
  • h(x) = 5(0.5)x + 0.5 has a y-intercept of 0.5.
  • h(x) = (0.5)x + 1 has a y-intercept of 1.
  • h(x) = 0.5(2)x + 0.5 has a y-intercept of 0.5.
