Question

What are the domain and range of the function f(x) = 3x + 5?

Answer 1

Answer:

D: (-∞, ∞)

R: (-∞, ∞)

Step-by-step explanation:

All linear equations have infinite domains and ranges. This is because they are endless, they keep going on forever and ever. When you graph this function, it's a straight line with no limits. If you decide to plot f(1000000), you will have a definite point where the line touches x=1000000. It will go on forever.
