On the graph of the function \(f(x)=x^3\), what is the value of \(y\) when \(x=2\)?

Answer and explanation

Correct answer: 8

For a function graph, \(y=f(x)\). Substituting \(x=2\) gives \(y=2^3=2\times2\times2=8\), so the correct answer is 8. Values such as 6 or 9 may result from incorrectly calculating the cube. Exam tip: \(x^3\) means multiplying \(x\) by itself three times, not multiplying it by 3.
