How does the graph of \(f(x)=\frac{1}{2}x^2\) compare with the graph of \(y=x^2\)?

Answer and explanation

Correct answer: Vertically compressed

In \(f(x)=\frac{1}{2}x^2\), every \(y\)-value of the parent function \(y=x^2\) is multiplied by \(\frac{1}{2}\). Thus, the graph is vertically compressed toward the \(x\)-axis and the parabola appears wider. It is not shifted left or down because there is no change inside \(x\) and no constant term has been added. Exam tip: when \(0<a<1\), the graph of \(y=ax^2\) is vertically compressed.
