Hi, can anyone convert this slope-intercept equation into function notation? Slope-intercept: y=1/2x+-2
Function Notation: ?

The maximum distance (in nautical miles) that a radio transmitter signal can be sent is represented by the expression 1.23h√, where h is the height (in feet) above the transmitter. estimate the maximum distance x (in nautical miles) between the plane that is receiving the signal and the transmitter. round your answer to the nearest tenth.
