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 ...

4x + 3\) and draw its graph for values of \(x\) from –2 to 5. Plot the \(x\) and \(y\) values as coordinates and join them with a smooth curve. This is a typical shape for a quadratic function.
