how to find domain and range of functions can anyone explain me step wise,,,
Here is the link for the answer to your query:
Assume f(x) = y
y = 2-3x
3x = 2-y
= x = (2-y)/3
Range of a function f(x) is the values of y which satisfy x. To find range of an equation given in terms of x, we assume f(x) = y and then write the equation in terms of y.
By solving the equation x = (2-y)/3, we get Range=All real numbers, or Range = (-,)
