Very short answer questions and solutions
Problem
If the function is defined by
f(x) = 3x – 2, x > 3,
f(x) = x^2 – 2, – 2 < or = x < or = 2
f(x) = 2x + 1,. x < – 3
then find the values if exist of f(4), f(2.5), f(- 4), f(0) and f(- 7).
Problem
If A = {0, π/6, π/4, π/3, π/2} and f : A to B is a surjection defined by f(x) = cos x then find B.
Problem
Determine whether the function f : R to R defined by f(x) = x, if x > 2, f(x) = 5x – 2, if x < or = 2 is an injection or surjection.
Problem
If f : R to R, g : R to R are defined by f(x) = 4x – 1 and g(x) = x^2 + 2 then find
