Exponential function using 2 points

Web2 days ago · Output. 2^2 = 4. In the above example, we declare a variable x with a value of 2, which is the exponent we want to calculate the base-2 exponential of. We then use the bitwise shift operator << to left shift the number 1 by x bits, which is equivalent to 2^x. The result is stored in the result variable, and we then print the result using the ... WebDec 9, 2016 · The general form for an exponential function is g ( x) = a b x, where a is the intercept (note that g ( 0) = a) and b is the ratio term. In this case, we have g ( x) = 5 8 ⋅ 2 …
