2023 WAEC FURTHER MATHEMATICS ESSAY (THEORY) ANSWERS:

 

3. To solve this problem:

 

(a) We know that the inverse function of f(x) is given by:

 

x = f^(-1)(y)

 

Therefore, we need to solve the given equation for y to find the inverse function:

 

y = -6x^(1/4)

 

So the function f(x) is:

 

f(x) = y = -6x^(1/4)

 

(b) We need to find the value of x such that f(x) = 5. Substituting the function f(x) from part (a), we get:

 

-6x^(1/4) = 5

 

Dividing both sides by -6, we get:

 

x^(1/4) = -5/6

 

Raising both sides to the fourth power, we get:

 

x = (-5/6)^4 = 0.4823

 

Therefore, the value of x for which f(x) = 5 is approximately 0.4823.
