Function evaluating

Question

Eevaluate the function ×=3. Round the answer to three decimal places. In the space provided,type the answer without any spaces between the letters,numbers,or symbols. f(×)=2e exponent x

Answer 1

Evaluating a function means putting in a number for x and finding out what the result equals. This question asks us to substitute 3 for x:

f(x) = 2e^x

f(3) = 2e³

In some classes you can leave the result as 2e³, but if you need a numerical approximation you can do it on a calculator to get 40.17
