Final answer:
To find the value of f(x) when x=12, substitute x=12 into the given function f(x) and calculate the expression.
Step-by-step explanation:
Function evaluation refers to the process of determining the output of a function for a given input. In mathematical notation, if you have a function f(x), evaluating the function at a specific value of x involves substituting that value into the function and computing the corresponding output. To find the value of f(x) when x=12, we substitute x=12 into the given function f(x)=x3-5x2+6x-3+1/x.
So, f(12)=123-5(12)2+6(12)-3+1/12.
Calculating this expression gives us the value of f(12).
