Which of the following describes the transformation of g of x is equal to 3 times 2 raised to the negative x power plus 2 from the parent function f of x is equal to 2 to the x th power ?

Starting with f(x) = 2^x, replacing x with −x gives 2^(−x), which reflects the graph across the y-axis. Multiplying by 3 stretches it vertically by a factor of 3, and adding 2 shifts it 2 units up. Therefore, the transformation is the one described in choice B.
