Find the sum and difference functions f + g and f – g for the functions given.
f(x) = 2x + 6 and g(x) = 2x  6
f(x) = x^2  x and g(x) = 3x + 1
f(x) = 3x^3  4 and g(x) = x^2 + 3
State the domain and range for the sum and difference functions in #3.
Find the product and the quotient functions for the functions given:
f(x) = 2x + 6 and g(x) = x + 3
f(x) = x^2 + 3x  4 and g(x) = x  1
f(x) = sqrt(x+1) and g(x)= sqrt(x1)
State the domain and range for each resulting function in #5.
Please explain and show all work. Math isn't my best topic!!!

they give you f and g. Is there some difficulty finding f+g, etc.?
Post what you got, and where you get stuck.
