    Here are my answers but I just want to double check: 1. I think the y-values are always positive is false. 2. I think the y-values are positive when x is positive is true. 3. I think the y-values are all positive when x is negative is false. 4. I think the y-value at x = 0 is 0 is false. 5. I think the y-value at -2 is -17 is true. 6. I think the largest y-value for x between -3 and 3 is 58 is true. 7. I think the smallest y-value for x between -3 and 3 is 58 is false. 8. I think the y-values are all negative when x is negative is true.
