Hey there!

f(x) = 3(2)^x

f(x) = 3(2)^-1

y = 3(2)^-1

y = 3 * 2^-1

y = 3 * 1/2

y = 3/1 * 1/2

y = 3(1) / 1(2)

y = 3/2

y ≈ 1 1/2


Thus, your answer is: y = 3/2 or y = 1 1/2


[EITHER OF THOSE SHOULD WORK BECAUSE THEY ARE BOTH EQUIVALENT TO EACH OTHER]

Good luck on your assignment & enjoy your day!
