Question1: Find the domain and range of the function y=x2-3x-4/x+1, We can say that the function is not defined at x=-1, Because when we substitute -1for x, we get zero in the denominator, So, the domain is all real numbers except -1, Substitute the x=-1 in the above equation, This means, the function is not defined when y=-5 and x=-1, Therefore the range of the function is {y belongs to R | y=!-5} and domain is {y belongs to R | x=!-1}. We do this because only nonnegative numbers have a real square root, in other. The range is found in a similar fashion to the domain, but instead of writing the interval as beginning at the smallest x-value and ending at the largest x-value, we write it as starting at the smallest y-value and ending at the largest y-value.
