The x-intercept of the function is: 6
The y-intercept of the function is: 80
What is the X-intercept and Y-intercept of a Function?
Given two variables, x and y, representing two quantities in a function:
- the x-intercept is the value of variable x of the function when its corresponding y-value is zero (0).
- the y-intercept is the value of variable y of the function when its corresponding x-value is zero (0).
Thus, given the function in the image below, where:
- y represents the amount of money Toby owed his friend
- x represents the time (number of weeks)
Thus, the value of x (weeks) when y (amount of money) is zero is 6 weeks.
Also, the value of y (amount of money) when the value of x (weeks) is zero is $80.
Therefore, we can conclude that:
The x-intercept of the function is: 6
The y-intercept of the function is: 80
