f(4)

Given the function \( f(x) = 2x + 3 \), we need to find \( f(4) \).

To do this, substitute \( x = 4 \) into the function:

\[
f(4) = 2(4) + 3 = 8 + 3 = 11
\]

Thus, \( f(4) = 11 \).

Here are 5 related questions for further exploration:

1. What is \( f(0) \) for the function \( f(x) = 2x + 3 \)?
2. How would you find \( f(x) \) if the function was \( f(x) = 3x + 1 \)?
3. What is the slope of the line represented by \( f(x) = 2x + 3 \)?
4. What is the y-intercept of the function \( f(x) = 2x + 3 \)?
5. How do you find the inverse of the function \( f(x) = 2x + 3 \)?

**Tip:** In linear functions like \( f(x) = 2x + 3 \), the coefficient of \( x \) represents the slope, and the constant term represents the y-intercept.

Discover how to find the value of f(4) for the linear function f(x) = 2x + 3 with a clear and detailed solution. This algebraic problem explores key concepts related to linear functions, suitable for students in Grades 6-8.
