The vertex of a parabola given by the equation y = ax^2 + bx + c is given by the point (-b/2a, f(-b/2a)).

In the equation y = x^2 + 3x, a = 1 and b = 3.

So, the x-coordinate of the vertex is -b/2a = -3/(2*1) = -1.5.

Substitute x = -1.5 into the equation to find the y-coordinate of the vertex:

y = (-1.5)^2 + 3*(-1.5) = 2.25 - 4.5 = -2.25.

So, the vertex of the parabola y = x^2 + 3x is (-1.5, -2.25).

The vertex of a parabola given by the equation y = ax^2 + bx + c is given by the point (-b/2a, f(-b/2a)).

In the equation y = x^2 + 3x, a = 1 and b = 3.

So, the x-coordinate of the vertex is -b/2a = -3/(2*1) = -1.5.

Substitute x = -1.5 into the equation to find the y-coordinate of the vertex:

y = (-1.5)^2 + 3*(-1.5) = 2.25 - 4.5 = -2.25.

So, the vertex of the parabola y = x^2 + 3x is (-1.5, -2.25).
