Domain ℝ range 1 the domain is how much the function takes x wise in the horizontal axis. Any real value of x i e x in rr or oo oo range. In the example value can be calculated for every x 0.

The range is set of all values y which the function takes. Use the graph. Equating the denominator to zero and solving gives the value that x cannot be.

The range is how much the function. This website uses cookies to ensure you get the best experience on our website. The domain of a function is the largest subset of real numbers rr for which the function s value can be calculated.

The domain of the expression is all real numbers except where the expression is undefined. The denominator of y cannot be zero as this would make y undefined. If x 0 then you would have to divide by zero which is not defined.
