This question is based on the solving equation of one variable. Hence, the value of f(8) is 3 by using given expression f(x) = x - 5.
Given that:
f(x) = x - 5
We need to determined the value of f(8) by using the given expression.
It is given that,
f(x) = x - 5
Now, finding the value f(8), by putting the x is equal to 8 in given expression. Solve it further,
We get,
f(x) = x - 5
Now putting the value x is equal to 3.We get,
f(8) = 8 - 5
Therefore, f(8) = 3
Hence, the value of f(8) is 3 by using given expression f(x) = x - 5.
