Based on the graph shown above, a formula for the function is
.
In Mathematics and Euclidean Geometry, a radical function, cubic function or a cube root function can be represented by using the following mathematical equation:
or

where:
- h represent the horizontal shift.
- k represent the vertical shift.
Based on the graph shown above, we can logically deduce that the parent function was shifted to the right by 2 units and up 1 unit. Therefore, we would determine the value of a by using these values and the x-intercept (3, 0);
![f(x)=a\sqrt[3]{x-h} +k\\\\0=a\sqrt[3]{3-2} +1\\\\0=a+1\\\\a=-1](https://img.qammunity.org/2023/formulas/mathematics/high-school/dkaidpqe2hsitehs025dczmupdz3hyk2z2.png)
In this context, an equation for this cubic function can be written as follows;
![f(x)=a\sqrt[3]{x-h} +k\\\\f(x)=-1 \cdot \sqrt[3]{x-2} +1\\\\f(x)=-(x-2)^3+1](https://img.qammunity.org/2023/formulas/mathematics/high-school/57xhhezgal33q9exoh0uj5cs8qrmm5s34m.png)
