is not a linear function. It's a quadratic function. Its graph is a parabola. Parabolas are endless curves with a smiley mouth shape (if the number in front of the is positive), or a frowning mouth shape (if the number in front of the is negative).
In this case, you got a frowny graph.

You could have asked about how to find the axis of symmetry, or the coordinates of the vertex, or even the equation of the directrix.
I do not want to give you more complication than you wanted, but I do not know what you needed.
The axis of symmetry is the line with the equation , based on the coefficient of the x (1) divided by (-2) and divided by the coefficient of the , (-3).
The y-coordinate of the vertex can be found by substituting in the function, and calculating the y value.
