Question

determine the domain of each of the following.
F(x)=4x+4
F(x)=x-3/x^2-16
F(x)=squ3x-6

Answer 1

Help

Answer 2

first : - all real values of x
second:- all real values except x = -4 and x = 4
third:- is that the square of (3x - 6) ?

Answer 3

thanks

Answer 4

and yes it is

Answer 5

what would be the 3rd one

Answer 6

i think its all real x except x = -2
because that would make 3x-6 = 0

Answer 7

- ok i just checked - square of 0 is 0
so domain of third function is all real x

Answer 8

thanks could you answer these
Evaluate the following given f(x) = 4x + 3 and g(x) = x2 + 4x – 1. Determine the domain of each.
9. f(4)
10. g(2)
11. f(x + 3)
12. g(x + 2)
13. (f + g)(x)
14. (f – g)(x)
15. (fg)(x)
16. (f/g)(x)
