Question

Let f be a one-to-one function whose inverse function is given by the formula
f^(-4)(x)=x^5+2x^3x+1
a. Computer f^-1(1) and f(1)
b. computer the value of x such that f(x)=1
C. Computer the value of y such that f^-1(y)=1

Please help me solve this problem.

Answer 1

i made error in typing the function.
it is

f^-4(x)=x^5+2x^3+3x+1

Answer 2

I have heard of f^(-1)(x) as the inverse of f(x) but I have no idea what wou mean by f^(-4)(x)

Answer 3

oh yeah that was an error. sorry about that.
it is f^(-1)(x)=x^5+2x^3+3x+1
