Q. Find the coordinates of the vertex of the following parabola algebraically. Write your answer as an (x,y) point.y=2x2−12Answer:
Identify Coefficients: To find the vertex of a parabola in the form y=ax2+bx+c, we can use the vertex formula x=−2ab. In this equation, y=2x2−12, there is no bx term, so b=0.
Calculate x-coordinate: Using the vertex formula x=−2ab, we substitute b=0 and a=2 into the formula to find the x-coordinate of the vertex.x=−2⋅20x=0
Find y-coordinate: Now that we have the x-coordinate of the vertex, we need to find the corresponding y-coordinate by substituting x back into the original equation.y=2(0)2−12y=−12
Vertex Coordinates: The coordinates of the vertex are therefore (0,−12).
