The solutions to f(x) = 64 is x = 7 and x = –7.
Solution: 
Given data:
 – – – – (1)
 – – – – (1)
 – – – – (2)
 – – – – (2)
To find the solutions to f(x) = 64.
Equate equation (1) and (2), we get

Subtract 15 from both sides of the equation.



Taking square root on both sides of the equation, we get
x = ±7
The solutions to f(x) = 64 is x = 7 and x = –7.
