Q. Find the equation of the axis of symmetry of the following parabola using graphing technology.y=x2+8Answer:
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+8, the coefficient a is 1 and there is no x term, so b=0.
Substitute into Formula: Substitute the values of a and b into the formula for the axis of symmetry: x=−2ab=−2⋅10=20=0.
Find Equation of Axis: The equation of the axis of symmetry is therefore x=0, which is a vertical line passing through the origin.
