The value of f(3) is 10
Step-by-step explanation:
Given that the function rule is

We need to determine the value of f(3)
The value of f(3):
The value of f(3) can be determined by substituting
in the function rule

Thus, we have,

Simplifying the values, we get,

Adding the value, we get,

Thus, the value of f(3) is 10
