Answer:

9

Step-by-step explanation:

So we have the function:

[tex]f(x)=x+4[/tex]

To find f(5), substitute 5 for x. Thus:

[tex]f(5)=5+4[/tex]

Add:

[tex]f(5)=9[/tex]

So, our answer is 9.

And we're done!

Hey there! I'm happy to help!

A function is kind of like a machine you put a number into and then it changes it and gives you a new number. This function is called f, and x is the number you put into it. So, if we have f(5), this means that 5 is our input that the function will change.

We see that f(x)=x+4. This means that f(5)=5+4, which is just equal to 9.

Therefore, f(5)=9.

Have a wonderful day! :D
