Find the domain and range of the function
f(x)=
-3x-2 x less than 4
3/4x-1 x greater than or equal to 4

relation function
Let f: X→X such that f(f(x)) = x for all x∈X. then
1) f is one to one and onto
2) f is one to one but not onto
3)f is onto but not one to one
4) f need not be either one to one or onto
True or false. If true, why? If false, what is a counter example, and can you explain why it contradicts? Please
If f and g continuous function on [a,b] then (upper: b, lower a)∫f(x)g(x)dx=[(upper: b, lower a)∫f(x)dx]*[(upper: b, lower a)∫g(x)dx].
