If we knew for sure what 'a' is, and what parabola you're talking about, and how
those two things are related, we might have a pretty good chance of answering
this question. Without that info, all we can do is speculate.
To determine the sign of the sum when adding a positive number and a negative number, compare their absolute values. If the positive number has a greater absolute value, the result will be positive; if the negative number has a greater absolute value, the result will be negative. If the absolute values are equal, the result will be zero.
No. All positive numbers are greater than zero and all negative numbers are less than zero. Therefore, all positive numbers are greater than all negative numbers. That said, there is a such thing as absolute value, which is how far a number is from zero. For example the absolute value of -10 is 10. The absolute value of a negative number can be greater than that of a positive number.
Any number that is greater than 14 or less than -14 will have an absolute value greater than 14. Mathematically expressed as if |n| > 14 then n > 14 or n < -14.
If the signs are the same, add the absolute values and keep the sign. If the signs are different, subtract the lesser absolute value from the greater absolute value and keep the sign of the number with the greater absolute value.

If the number in front of x squared is a number greater than 1, the parabola will start becoming thinner. The opposite occurs when the number is a fraction.

The absolute value of a number is the distance to zero. When adding which ever number has the greater absolute value will determine the sign of the answer.

To determine the sign of the sum when adding a positive number and a negative number, compare their absolute values. If the positive number has a greater absolute value, the result will be positive; if the negative number has a greater absolute value, the result will be negative. If the absolute values are equal, the result will be zero.
The absolute value of the answer will be greater than the absolute value of the original.
If the absolute value of a negative number is greater than the absolute value of a positive number, then on addition we will get a negative number. e.g. -4 + 1 = -3 If absolute value of positive number is greater, then the result is positive. e.g. 5 + (-4) = 1
The absolute value of 3 is +3. No negative number can have a value greater than +3.
No. All positive numbers are greater than zero and all negative numbers are less than zero. Therefore, all positive numbers are greater than all negative numbers. That said, there is a such thing as absolute value, which is how far a number is from zero. For example the absolute value of -10 is 10. The absolute value of a negative number can be greater than that of a positive number.
