Answer: - 3
Explanation: In this problem, we're given the function f (x) = 2x + 1 and we're asked to find f (-2).
To find f (-2) or the value of the function or the value of the function when x = - 2, we simply substitute - 2 in for x in our function.
So we have f (-2) = 2 (-2) + 1 or - 4 + 1 which equals - 3.
So f (-2) or the value of the function when x = - 3 is - 3.
