Buatlah grafik fungsi f: x 3x+1 atau f(x) = 3x + 1

Here is the graph of the function \( f(x) = 3x + 1 \). You can see the line has a slope of 3 and a y-intercept at 1, which means it crosses the y-axis at \( (0, 1) \).

Do you want more details or have any questions about this function or the graph?

Here are 5 related questions to explore:
1. How do you determine the slope of a linear function from its equation?
2. What is the y-intercept of the function \( f(x) = 3x + 1 \)?
3. How does changing the slope affect the steepness of the graph?
4. How would the graph change if the function was \( f(x) = 3x - 1 \)?
5. What happens to the graph if the coefficient of \( x \) is negative?

**Tip:** For any linear equation in the form \( f(x) = mx + b \), the coefficient \( m \) represents the slope, and \( b \) represents the y-intercept.

Explore the graph of the linear function f(x) = 3x + 1, which has a slope of 3 and a y-intercept of 1. Learn how to interpret the slope and y-intercept, and how to graph this function step by step. Suitable for students in Grades 6-8.
