Warm-up

Can you arrange the functions \(f(x)=x^2\), \(f(x)=-1\), \(f(x)=x\) and \(f(x)=x^3\) in the table below so that they have the properties stated in each cell?

Graph is straight

\(y\)-axis is a line of symmetry

\[f(x)= \cdots\]

Graph is straight

\(y\)-axis is not a line of symmetry

\[f(x)= \cdots\]

Graph is not straight

\(y\)-axis is a line of symmetry

\[f(x)= \cdots\]

Graph is not straight

\(y\)-axis is not a line of symmetry

\[f(x)= \cdots\]

Can you explain why each function is in each cell?

Which other functions could fit in the cells of this table?
