HEEELP let f(x) =1/x-3 and g(x)=√x+5. What is the domain of (f o g)(x)

Options

a) [-5,-4)U(-4, inf)

b) [-5,-3)U(-3,inf)

c)[-f,4)U(4,inf)

d)[-5,3)U(3,inf)

(c)

Step-by-step explanation:

Given

Here,

To get , replace in by

Using and  it can be concluded that the domain of is all real numbers except 0.

Therefore, its domain is given by

Option (c) is correct.

what?

step-by-step explanation:

what do you need with. i love quadrants. can you tell me ?

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
