Give the domain of each of the following functions in interval notation.
Domain can be found from a graph and from the function
equation. There are four instances that we will study in Pre-Cal
that have restrictions on the domain. The domain for any other
function is "All Real Numbers" (R)

2. f(x) = x2 - 5x + 6
1. f(x) = 5x - 2
3.
1
4. f(x) = √5x-2
f(x) = 2x - 5
5. f(x) = ∛5x - 2
*If this type is in the denominator of a fraction, the only thing
that changes about the answer is that the brackets will become
parenthesis
