Prove that if x is real, the expression `((x-a)(x-c))/(x-b)` is capable of assuming all values if `agtbgtc` or `altbltc`.

For real x, the function (x-a)(x-b)/(x-c) will assume all real values provided

Number of integers in the range of a for which the expression y=((x-1)(x-5))/(x-a) is capable of taking all real values for x in R, is

If x is real,the expression (x+2)/(2x^(2)+3x+6) takes all value in the interval

For x in R, the expression (x^(2)+2x+c)/(x^(2)+4x+3c) can take all real values if c in

f(x)=((x-1)(x-4))/(x-a)) will assume all real values provided
