Q. Find the equation of the axis of symmetry for the parabola y=x2−4x+1. Simplify any numbers and write them as proper fractions, improper fractions, or integers.__
Identify coefficients: Identify the coefficients a and b from the quadratic equationy=ax2+bx+c. The given equation is y=x2−4x+1, which can be compared to the standard form y=ax2+bx+c. Here, a=1 and b=−4.
Calculate axis of symmetry: Use the formula for the axis of symmetry, which is x=−2ab, to find the axis of symmetry for the parabola.Substitute the values of a and b into the formula.x=−2⋅1−4x=24x=2
Write equation of axis: Write the equation of the axis of symmetry.The axis of symmetry is a vertical line, so its equation is of the form x=constant.Therefore, the equation of the axis of symmetry for the given parabola is x=2.
