Answer: The zero of a function is the value of y when x equals zero.
Step-by-step explanation: The zero of a function is the value of y when x equals zero. It is also known as an x-intercept. In this case, I believe there is a mistake in this question, as when x equals 0, it shows on the table that it is 6. The zero of the function should be (0,6). They say that the zero is -2, but that is not possible as that would be the y-intercept, where y is zero.
For your homework, I would ask the teacher about the question as it seems to be an error. You can use the response above, since it is correct, but make sure to check with your teacher for review.
