{{ printedBook.courseTrack.name }} {{ printedBook.name }} Let us start by listing the characteristics of the quadratic function in the graph.

- The curve has an absolute minimum.
- The curve intersects the positive part of the $y$-axis.

With this information, we can exclude some functions.

The second degree curve has an absolute minimum which means that the coefficient in front of $x_{2}$-term must be positive. Therefore, we can exclude **B**.

Because the curve cuts the positive part of the $y$-axis the constant term also has to be positive, which means that you can exclude the function **C** which has the constant $-6.$

The only function left is function **A**.
