Question

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(x-1)

State the domain and range for each resulting function in #5.

Please explain and show all work. Math isn't my best topic!!!

Answer 1

they give you f and g. Is there some difficulty finding f+g, etc.?

Post what you got, and where you get stuck.
