How to use the eval statement with a list of strings?

How can I use the eval statement with a list of strings?
Example: a list ["math.sin", "math.cos", "lambda x: x * 2", "lambda x: x ** 2"] and a value x = 1.
My task is to return a list with results of the expressions.

import math

exprs = ["math.sin", "math.cos", "lambda x: x * 2", "lambda x: x ** 2"]
x = 1

functs = map(eval, exprs)
# or: functs = (eval(e) for e in exprs)

results = [f(x) for f in functs]
