In order to calculate the inverse function log -1 y on the calculator enter the base b 10 is the default value enter e for e constant enter the logarithm value y. Thus the antilog is the inverse function of log. X logb.
Replace the function notationf x fleft x rightf x byy yy.
Thus the antilog is the inverse function of log. Since log and antilog are inverse functions then this means that x b y b log b x and y log b x log b b y. Enter the antilog number and its base value in its appropriate field. In order to calculate the inverse function log -1 y on the calculator enter the base b 10 is the default value enter e for e constant enter the logarithm value y.
