How is the graph of \(f(x)=x^3-2\) shifted compared with the graph of \(y=x^3\)?

Answer and explanation

Correct answer: 2 units down

In \(f(x)=x^3-2\), the constant \(-2\) is applied outside the function, so every \(y\)-value decreases by 2. Therefore, the graph of \(y=x^3\) shifts 2 units downward. This is not a horizontal shift; horizontal changes occur inside the input, such as in \((x-2)^3\). Exam tip: a constant added or subtracted outside a function shifts its graph vertically up or down, respectively.
