Question

How do you find the domain and range of `F (X) = (4)/(x-3)`?

Answer 1

y = 4/(x - 3)

Explanation:

When x = 3 --> y goes to `+- infinity`.
When `x = +-` infinity, y --> 0.
y-intercept when x = 0 --> `y = - 4/3`
graph{4/(x - 3) [-10, 10, -5, 5]}
Domain of x: (-infinity, 3)) and (3, +infinity)
Range of y: (-infinity, 0) and (0, +infinity)
