Find the vertex of the following parabola: *

Calculate x-coordinate: To find the vertex of a parabola given by the equation $y = ax^2 + bx + c$ , we can use the vertex formula $x = -\frac{b}{2a}$ for the x-coordinate of the vertex. $\newline$ In our equation, $a = 1$ and $b = -2$ . $\newline$ Let's calculate the x-coordinate of the vertex. $\newline$ $x = -(-2)/(2\cdot1) = \frac{2}{2} = 1$
Find y-coordinate: Now that we have the x-coordinate of the vertex, we can find the y-coordinate by substituting $x$ back into the original equation. $y = (1)^2 - 2*(1) - 3 = 1 - 2 - 3 = -4$
Identify vertex point: We have found both coordinates of the vertex. The vertex of the parabola is at the point $(1, -4)$ .
