The value of x is - 24.
Explanation:
Given that , the function f(x) as
f(x) = x
We need to find out the value of x if f(x) = -24
According to given statement, the value of function is equal to the value of x that satisfy the function. So from the given data,
f(x) = - 24
But we know that f(x) = x, so the value of 'x' must be as below,
x = - 24
Hence, the value of x is - 24.
