Find gof and fog if `f: RrarrR and g: R rarr R` are given by
f(x) = cos x and g (x) `=3x^2`
Show that `gof ne fog`

Let f: Rrarr R and g: RrarrR be defined by f(x) = x^2 and g(x) = x + 1 . show that gof is not equal to fog .

Find fog if f(x)= x-2 and g(x) = 3x

Find gof if f(x)= 8x-2 and g(x) = 2x

If f(x) = sin x and g(x) = 2x, find fog.

Find fog if f(x) = |x| and g(x) = |5x-2|

If f : R rarr R and g : R rarr R be two mapping such that f(x) = sin x and g(x) = x^(2) , then find the values of (fog) (sqrt(pi))/(2) "and (gof)"((pi)/(3)) .

If f, g: Rrarr R are defined by f(x) = x^2 + 3x+1,g(x) = 2x – 3 then find gof .

Find gof and fog, if f(x) = |x| and g(x) = |5x -2|

Find gof and fog if : f(x) =|x| and g (x) = (5x-2)

If f, g: Rrarr R are defined by f(x) = x^2 + 3x+1,g(x) = 2x – 3 then find fog .
