Final answer:
In the standard quadratic equation Ax^2 + Bx + C = 0, the constant term C represents the y-intercept of the function, which is where the graph crosses the y-axis.
Step-by-step explanation:
In the standard form Ax^2 + Bx + C = 0, the y-intercept of the function is represented by the constant term C. The y-intercept is the value of y when x is zero, meaning it is where the graph of the function crosses the y-axis. To find the y-intercept for a quadratic equation, you can plug in x = 0 into the equation, which simplifies to y = C. Therefore, the constant C directly tells us the y-intercept.
