so.. what value of "x" makes x+4 to 0?
the domain will be, all real numbers, except that value
about the range, "y" will take, whateve "x" can provide.. in this case... I think is all real numbers, except 0, because, if you give a few big values to "x", the fraction will simply have a bigger and bigger denominator, making the fraction smaller and smaller, ever approaching 0, but never getting there
So you would add 12 to the other side of the equation, and 9+12=21, so x=21.
I dont know how to write this on my phone but its 1500<, except the arrow has the line under it to represent at least.
