How to find domain and range of a function algebraically?
Answered by admin @
Another way to find the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values.
if you write down y=f(x) and then solve the equation for x, giving something of the form x=g(y). you’ll then Find the domain of g(y), and this will be the range of f(x).If you can't seem to solve for x, then try graphing the function to find the range as I said earlier.
