The function you provided is $F(x) = 3x - 7$.

Key features of this linear function:

• Slope (m): The coefficient of $x$, which is 3. This means for every unit increase in $x$, $F(x)$ increases by 3.
• Y-intercept (b): The constant term, which is -7. This is the value of $F(x)$ when $x = 0$, meaning the line crosses the y-axis at $(0, -7)$.
• Domain: Since this is a linear function, the domain is all real numbers, $(-\infty, \infty)$.
• Range: Similarly, the range is also all real numbers, $(-\infty, \infty)$.
