The equation of y = 2³ with the described transformations is y =

The original equation is
. Let's apply the he given transformations step by step.
1. Vertical stretch by a factor of 3: This means multiplying the entire function by 3. The equation becomes
.
2. Horizontal shift 4 units to the right: To shift a function to the right, you replace with (xh), where h is the amount of shift. So, shifting 4 units to the right means replacing 2 with (x - 4). The equation becomes
.
3. Vertical shift 3 units down: To shift a function down, you subtract the amount from the function. So, shifting 3 units down means subtracting 3 from the entire function. The equation becomes

Therefore, the equation of y = 2³ with the described transformations is y =
