Which of the following represents the graph of f(x) = 2x + 2? i will give a medal if you cooperatively

Our function is:
f(x) = 2^x + 2

To find which graph represents this function we should find at least 2 points. We take some value of x we want and calculate y for it. And do that at least 2 times (can be done 1 time but its likely that some graph match in some points)

for x = 0 we get
f(x) = 3

for x = 1
f(x) = 4

we can also note that f(x) cannot be less than 2 because 2^x is always greater than 0, and that as x increments f(x) increments. With all of this in mind answer is last graph.

Answer is graph D
