Simple Function Question, Can't Figure Out How Answer is Achieved

In summary, a simple function takes an input value and performs a specific task or operation on it to produce an output value. The type of function can be determined by the operation being performed on the input value and the notation f(x) or g(x) represents the relationship between the input and output values. If you are having difficulty solving a simple function, it is helpful to break it down into smaller steps or seek assistance from outside resources.

1. The problem statement:
Pretty straight forward:
f(x)=1/x
Simplify 2f(x)+3
Evidently, the answer is (2+3x)/x but I don't know how to find that,

2. Homework Equations :
None, as far as I know

3. The Attempt at a Solution :
2f(x)+3 = 2(1/x) + 3 = 2/x + 3
I'm of course missing some simple step or identity that could help me, but I can't come up with any thoughts on how to navigate to the correct answer.

Any help will be greatly appreciated, thanks!

You have (2/x) + (3/1).

How do you add two fractions together?

Related to Simple Function Question, Can't Figure Out How Answer is Achieved

1. How do I determine the input and output of a simple function?

The input of a simple function is the value that is being plugged into the function, while the output is the resulting value after the function is applied to the input.

2. What is the purpose of a simple function?

A simple function is used to perform a specific task or operation on an input value and produce an output value.

3. How do I identify the type of function being used?

The type of function being used can be identified by looking at the operation being performed on the input value. For example, if the function is adding two numbers together, it is an addition function.

4. What does the notation in a simple function represent?

The notation in a simple function represents the relationship between the input and output values. It is typically written as f(x) or g(x) where x is the input value.

5. How do I solve a simple function if I can't figure out the answer?

If you are having trouble solving a simple function, try breaking it down into smaller steps or using a different approach. You can also consult textbooks, online resources, or seek help from a tutor or teacher.
