(lambda (x) (+(*2 x)l))
(lambda (x) (+1 (* 2x)
(+ lambda (x) 1 (*2x))
(* lambda(x) (+2x1) E. None of the above
Answer is Right!
Answer is Wrong!
The correct answer is A. (lambda (x) (+(*2 x)l)).
In LISP, a function is defined using the lambda function. The lambda function takes two arguments: the name of the function and the body of the function. The body of the function is a list of expressions, which are evaluated in order.
In the expression (lambda (x) (+(*2 x)l)), the name of the function is x. The body of the function is (+(*2 x)l). This expression evaluates to 2x+l.
The other options are incorrect because they do not define a function. Option B, (lambda (x) (+1 (* 2x)), defines a function that takes one argument, x, and returns the value 1 + 2x. Option C, (+ lambda (x) 1 (*2x)), is not a valid LISP expression. Option D, (* lambda(x) (+2x1), is also not a valid LISP expression.
