Q. Find the equation of the axis of symmetry of the following parabola using graphing technology.y=−x2−2x−7Answer:
Identify Parabola Equation: The equation of a parabola in the form y=ax2+bx+c has an axis of symmetry that can be found using the formula x=−2ab. In this case, the parabola is y=−x2−2x−7, so we identify a=−1 and b=−2.
Substitute Values: We substitute the values of a and b into the formula for the axis of symmetry: x=−(−2)/(2∗(−1)).
Perform Calculation: Perform the calculation: x=(−2)2=−1.
Final Axis of Symmetry: The equation of the axis of symmetry is therefore x=−1.
