Final answer:
The y-intercept cannot be determined from the information given.
Step-by-step explanation:
The y-intercept of a function is the point where the graph of the function intersects the y-axis. It represents the value of the function when the input variable is zero. In the given information, there is no specific equation or graph provided to determine the y-intercept directly. Therefore, the y-intercept cannot be determined from the information given.
