For each pair of functions ff and gg, find the domain of ff and the domain of gg. indicate whether ff and gg are the
same function.
a. f(x) = x2 / x , g(x) = x
b. f(x) = x / x , gg(x) = 1
c. f(x) = 2x2 + 6x + 8 / 2 , g(x) = x2 + 6x + 8
d. f(x) = x2 + 3x + 2 / x + 2 , g(x) = x + 1
e. f(x) = x + 2 / x2 + 3x + 2 , g(x) = 1 / x + 1
f. f(x) = x4 − 1 / x2 − 1 , g(x) = x2 + 1
g. f(x) = x4 − 1 / x2 + 1 , g(x) = x2 − 1
h. f(x) = x4 − x / x2 + x , g(x) = x3 − 1 / x + 1
i. f(x) = x4 + x3 + x2 / x2 + x + 1 , g(x) = x2
