Question

Hey guys if you can help me i would really appreciate it!

F(x) = __3x+4___
5x+9

The domain of (f) contains all real numbers x , except x= ???????????

Answer 1

is this a division problem?

Answer 2

if it is, then the law states that we cannot under any circumstances divide by zero. It will rip a hole the size of nantucket into the very fabric of reality into which nothing can escape....

what would make the denominator, the bottom, equal zero?

Answer 3

haha ok, and yes it is!

Answer 4

would we multiply by zero

Answer 5

nope.... we would do this:

5x+9=0

5x +9-9 = 0-9

5x +0 = -9

5x = -9

5x/5 = -9/5

1x = -9/5

x cannot under any circumstances be allowed be equal to -9/5. So keep it out of the cupboards and make sure you dont feed it after midnight.....
