MHB Multiple Transformations of Functions

Click For Summary
To transform the function f(x) = x^3 into the new function, a horizontal shift of 3 units to the right and a vertical shift of 1 unit upward is required. The transformation can be expressed as f(x) = a(x-3)^3 + 1, where 'a' represents the stretch factor. Given the point (4, 1.5), the value of 'a' can be determined by substituting this point into the equation. This results in an equation that allows for the calculation of 'a', completing the transformation process. Understanding these transformations is crucial for accurately modifying the function.

I have to transform the first function which is f(x)=x^3 to the second function. First, I have to find each shift then combine those to make a new function equation. I've used desmos and I know that there is a horizontal shift 3 units to the right. There is a vertical shift up but I don't know how many units. And I believe there is a stretch. There are only 3 transformations. PLEASE HELP!

note the function center point $(0,0)$ is translated to $(3,1)$, a horizontal shift right 3 units and a vertical shift up 1 unit.

taking into account the horizontal & vertical shifts, we have ...

$f(x) = a(x-3)^3 + 1$

... where $a$ is the constant causing the stretch

using the point $(4,1.5)$, can you determine the value of $a$ ?
