Step-by-step explanation:
<u>Function Evaluation</u>
Given a function f(x) as an explicit expression, finding f(x=a) implies substituting the value of x by a in every instance it occurs.
We are given the function:
It's required to find f(10). We replace the x for 10:
Operating:
Thus, f(10)=290
The answer is 3/5.
