Let f(x) = 3x + 6 and g(x) = 2x^2. perform the function operation and then find the domain of the result.

(f + g)(x) =

what is the domain of (f+g)(x)?

(f+g)(x)=f(x)+g(x)=3x+6+2x^2
the domain will be all real numbers

Basically the inverse is when you reflect the function across the identity line, y=x

basically to find the inverse of a function
flip switch all x and y and solve for y, then replace y with finverse

f(x)=7x-13
y=7x-13
switch
x=7y-13
solve for y
x+13=7y
(x+13)/7=y

finverse=(x+13)/7

3rd one
quantity of x plus 13 over 7
