Graph the linear function $f(x)=5 x-6$, from its slope and its intercept. \begin{tabular}{|l|l|l|l|l|l|l|l|l|l|} \hline & & & & & & $\mid$ & $\mid$ & $\mid$ \\ \hline & & & & & & & & & \\ \hline & & & & & & & & & \\ \hline & & & & & & & & & \\ \hline & & & & & & & & & \\ \hline & & & & & & & & & \\ \hline & & & & & & & & & \\ \hline & & & & & & & & & \\ \hline & & & & & & & & & \\ \hline & & & & & & & & & \\ \hline \end{tabular}
Given the function $f(x)=2 x+x^{2}$, draw its graph to indicate the intersections with the axes, the coordinate of the vertex and the maximum or minimum value of the ordinate.
Intersection with the $x$-axis: $\qquad$ Intersection with the $y$-axis: $\qquad$
Intersection with the $y$-axis: $\qquad$
Minimum or maximum value of the ordinate: $\qquad$
Equation of the axis of symmetry: $\qquad$
