what is the domain of this function how did you find the domain.
f(x)=(2x-3)/(x+9)
The only thing we have to worry about is a division by zero.
That will happen when x = -9
so domain:
any real number of x, x ≠ -9
f(x)=(2x-3)/(x+9)
That will happen when x = -9
so domain:
any real number of x, x ≠ -9
