Question

Laura graphed the function below y = 1 / 2(One over two)x + 4

if the range of the function is restricted to 2 ≤ y ≤ 6, what is the domain?

Answer 1

Explanation:

y = 0.5x + 4

When y = 2, x = -4. (shown in graph)

When y = 6, x = 4. (shown in graph)

Hence the domain would be -4 <= x <= 4.
