State the domain and range of the following.
Why is the range greater than or equal to zero? Why isn't it (2, infinity)?
I've just started going through dilations, reflections and translations of different equations and now we are going through absolute functions.
Please show complete working out. All help will be appreciated.
I hope you know how the domain is found. Try showing your work if you were unable to find the domain.
