Question

If f(x)=2x+1,then f(-2)=

Answer 1

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.
