Q. Find the equation of the axis of symmetry of the following parabola using graphing technology.y=−x2+3Answer:
Identify Coefficients: The axis of symmetry of a parabola in the form y=ax2+bx+c is given by the formula x=−2ab. In the given equation y=−x2+3, we can identify a=−1 and b=0, since there is no x term.
Substitute into Formula: Substitute the values of a and b into the formula for the axis of symmetry. Since b=0, the formula simplifies to x=−0/(2∗(−1))=0.
Calculate Axis of Symmetry: The equation of the axis of symmetry is therefore x=0, which is a vertical line passing through the origin.
