1 show that a function f: RR defined by f(x) =47-5/3 is a one to one correspondence
2. Show that whether each of the following function is odd, even or neither of both;
a . f(x)= 6x² + 30
b. f(x)=1/4
f(x) = -20x2 - 15x+5
3. Given f(x) = 6x2 + 2x - 3 and gof (x)=x2 - 4x - 2, then find g(x), g(10) and fog(10)
