Identify Coefficients: Identify the coefficients of the quadratic equation.The quadratic equation is given by y=ax2+bx+c. In the equation y=x2−4x+5, we can compare it to the standard form and identify the coefficients as follows:a=1 (coefficient of x2)b=−4 (coefficient of x)c=5 (constant term)
Use Axis of Symmetry Formula: Use the formula for the axis of symmetry.The axis of symmetry for a parabola given by the equation y=ax2+bx+c is x=−2ab. We will substitute the values of a and b into this formula to find the axis of symmetry.
Substitute Values: Substitute the values of a and b into the formula.a=1b=−4x=−(−4)/(2⋅1)x=4/2x=2The axis of symmetry is the line x=2.
