The following code is supposed to retrieve a number that the user types and computes the exponential of that number, however the code doesn't work, because it has syntax error(s). import numpy as npy x = input() print (exp[x]) Check the error(s): Select one or more: a. input() is missing a string input('string') b. x is not a number c. The exponential function argument should be written inside round parentheses, not square brackets d. numpy's alias is incorrectly worded. e. exp is a function defined in numpy, so you need to write down the path (eg numpy_alias.exp()) f. You don't need to import numpy to use the exponential function g. You need to import an additional module to use the function input()
