Quadratic functions

The total mechanical energy $E$ of an object is given by the formula $E=mgh+\frac{1}{2}m{v}^2$, where $m$ is the mass of the object, $g$ is the acceleration due to gravity (about $10\mathrm{m}/{\mathrm{s}}^2$), $h$ is the height of the object above the ground and $v$ is the velocity of that object. Suppose that an object of the fixed mass $m$ moves horizontally in the constant height $h$ above the ground. Choose the graph, which could represent the dependence between the total mechanical energy ($E$) and velocity ($v$) of the object.
