thanks!!!!!

What if we have a negative?! ;o

F(x)= x+8+2

and x= -7.4

and the answer you get you have to square it

Thanks for teaching me all things math,

[goofguy316]

how would you find the domain of the function if:

f(x) = some function

g(x) = some function but has a restriction like x>4

If you are asked to find the domain of lets say, (f+g)(x) or (f/g)(x)

I looked at your video on composite functions but couldn't really grasp the idea of finding the domain of a function when there's a restriction. I would highly appreciate if you could help me out, you've been great help in your other videos. Thanks in advance!

I love u! My math teacher needs to retire =P

[basketballrobb]

Really helped me, thanks a lot! =D

@Bomberfun1 it means move the whole function down 19 units on the y-axis.
