Answer: (0, 3)

Step-by-step explanation:

The original function is

f(x) = e^x

If it is dilated by a fator of 2 and translated 1 unit upwards, it becomes

2e^x + 1

This is the same as

g(x) = 2f(x) + 1

Thus,

g(x) = 2e^x + 1

To find the y intercept, we woild substitute x = 0 into g(0). It becomes

g(0) = 2e^0 + 1 = 2 + 1 = 3

Thus, the correct oprion is

( 0, 3)
