What is the domain of f(x)= sqrt x - 7?
1 Answer | Add Yours
Domain of: `f(x) =sqrt(x) - 7`
We can not have negative values for a radical in a function therefore, our possible inputs for this function has to be anything greater than or equal to zero.
Can not have: `sqrt(-5)`
Therefore we say that domain is all real numbers greater than or equal to 0.
