Final answer:
The vertical intercept, also known as the y-intercept, is the point where a line crosses the y-axis. It is the value of y when x is equal to zero. In the equation for a straight line, y = mx + b, the intercept b represents the y-coordinate of the point where the line intersects the y-axis.
Step-by-step explanation:
The vertical intercept, also known as the y-intercept, is the point where a line crosses the y-axis. It is the value of y when x is equal to zero. In the equation for a straight line, y = mx + b, the intercept b represents the y-coordinate of the point where the line intersects the y-axis.
For example, if the equation of a line is y = 2x + 3, the intercept b is 3. This means that the line crosses the y-axis at the point (0, 3).
Therefore, to find the vertical intercept for the function f, you need the equation of the line or function.
