Question

Domain of function...is this correct?

Answer 1

no, its not correct

Answer 2

what makes 2x-5 = 0 ? since dividing by zero is bad we want to avoid it.

Answer 3

Set the denominator equal to zero and solve for x,
2x - 5 = 0
2x = 5
divide both sides by 2...
x = 5/2
so x cannot be 5/2 because the denominator would equal zero
No do you know the answer?
