For real x, the function `((x-a)(x-b))/(x-c)` will assume all real values provided a)`agtbgtc` b)`altbltc` c) `agtc ltb` d) `a le c le b`

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

If x is real then (x^(2)-x+c)/(x^(2)+x+2c) can take all real values if

If a,b,c are distinct positive numbers,then the nature of roots of the equation 1/(x-a)+1/(x-b)+1/(x-c)=1/x is a.all real real and is distinct b.all real and at leat two are distinct c.at least two real d.all non-real

If a

The function f(x)=x^(2)+bx+c , where b and c are real constants, describes

If f(x)=x has non real roots, then the equation f(f(x))=x (A) has all real and unequal roots (B) has some real and non real roots (C) has all real and equal roots (D) has all non real roots
