Question

Given the function y = -2ex , find y if x = 3.

Answer 1

Answer:

Assuming function is $y=-2*e*x$: y(3)= -16.31.

Assuming function is $e^x$$y=-2*e^x$: y(3)= -40.17

Step-by-step explanation:

These should both be simple enough to do with a calculator or simply googling, but if you must do it by hand, an easy trick to remember is that e is approximately equal to 2.718 so substitute that value wherever you see e. Then, just substitute 3 in for x and simply multiply.
