Q. y=x2−2x−3Find the vertex of the following parabola.
Calculate x-coordinate: To find the vertex of a parabola given by the equation y=ax2+bx+c, we can use the vertex formula x=−2ab for the x-coordinate of the vertex.In our equation, a=1 and b=−2.Let's calculate the x-coordinate of the vertex.x=−(−2)/(2⋅1)=22=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).
