| Draggable item | arrow_right_alt | Corresponding Item |
|---|---|---|
f(x) = (x+3)^{2} | arrow_right_alt | f(x) = \sqrt{x} |
f(x) = x^{3} | arrow_right_alt | f(x) = \sqrt[3]{x} |
f(x) = x^{2} | arrow_right_alt | f(x) = \frac{1}{2}x |
f(x) = x+3 | arrow_right_alt | f(x) = x-3 |
f(x) = 2x | arrow_right_alt | f(x) = \sqrt{x}-3 |
