All quadratic functions have the same type of curved graphs with a line of symmetry. The graph of the quadratic function \(y = ax^2 + bx + c \) has a minimum turning point when \(a \textgreater 0 ...

Look at the function z = y^2 / x and think about other possible functions we might need in the future. It can be hard to pre-set all kinds of functions (or combinations of x, y and z). So, here I came ...
