15.Consider the following functiontypoglycemia, which takes as input a valid strings, containing at least one character. It is intended to return a string formed by taking the first and last letter of each of the words in the input string, as well as the space in between words. Return 'Error' if the input string is only one word.

20.Given the function definition for computing the displacement of an object:

DEFINE calculate (a, b, c)

solution= a * c + 0.5 * b * c * c

RETURN solution

ENDDEF

And the following code statements:

x = 3

y = 12

z = 9

solution = calculate(x, y, z)

Which of the following statements is true after the call tocalculate( x, y, z)has completed execution?

-The order of inputs to the function call is unimportant; the function definition declares how the inputs are used. e.g.,

calculate(x, y, z) == calculate(y, x, z)

-a, b, and c are undefined.

-a = 3, b = 12 , and c = 9

-calculate is called with up to 3 variables.

-If the value of a changes inside the calculate function.,. the value of x will also be changed.
