Consider the function that maps non-negative real numbers to their positive square root. This function can be described by the formula {{MATH_125}} The domain is {{MATH_126}}, which we write in interval notation as {{MATH_127}}. The range is {{MATH_128}}. Here is a graph of {{MATH_129}}: {{CMD_130}} {{ENV_131}} {{COMMENT_132}} {{COMMENT_133}} {{COMMENT_134}} {{COMMENT_135}} {{CMD_136}} {{CMD_137}}
