Given f(x)=3x+5*f*(*x*)=3*x*+5 
find f(3)=*f*(3)=

Given the function \( f(x) = 3x + 5 \), you need to find \( f(3) \).

1. Substitute \( x = 3 \) into the function:
\[
f(3) = 3(3) + 5
\]

2. Simplify:
\[
f(3) = 9 + 5 = 14
\]

Thus, \( f(3) = 14 \).

Here are five related questions for further exploration:
1. What is \( f(0) \) for the function \( f(x) = 3x + 5 \)?
2. How do you find the inverse of the function \( f(x) = 3x + 5 \)?
3. What is the slope of the function \( f(x) = 3x + 5 \)?
4. How does the function change if the constant 5 is replaced with another constant?
5. Can you find \( f(a + b) \) for arbitrary values \( a \) and \( b \)?

**Tip:** Always check the value of the function by substituting directly to ensure accuracy.
