Determine the domain of each rational function, and express the rule for each function in an equivalent form in
lowest terms.
a. f(x) = x4 / x2
b. f(x) = 3x + 3 / 15x − 6
c. f(x) = x2 − x − 2 / x2 + x
d. f(x) = 8x2 + 2x − 15 / 4x2 − 4x − 15
e. f(x) = 2x3 − 3x2 − 2x + 3 / x3 − x
f. f(x) = 3x3 + x2 + 3x + 1 / x3 + x
