Question: how do you find the square root on a graphing calculator?
Answer: To access second function keys, use the yellow key marked "2nd," found in the upper left corner of the key pad. Press "2nd," and then the key below the desired function symbol. To find a square root using the TI-83 or TI-84, first push the "2nd" key and then the x2 key to access the square root function.
