The position of rational number AB on the number axis is known. For the formula | a | + 1, when a takes what value, it has the minimum value? What is the minimum value? --- a --- 0 -- B------

The position of rational number AB on the number axis is known. For the formula | a | + 1, when a takes what value, it has the minimum value? What is the minimum value? --- a --- 0 -- B------

From the number axis, we know that a < 0, so | a | + 1 > 1, so | a | + 1 has no minimum value
