Hello,
I badly need help with a question..
Just to start of by defining the functions.
f: Q -> R where f(x) = 0,2cos(pi*x)-7
g: N -> Q where g(x) = 5x/2
h(x) = f(g(x)) therefore h(x)= 0,2cos(5x*pi/2)-7
a) What is the range of h?
b) What is the domain of h?
c) Is h surjective?
I would be very glad if anyone could help me out..
