Q. Find the equation of the axis of symmetry for the parabola y=x2−25. Simplify any numbers and write them as proper fractions, improper fractions, or integers.__
Identify values of a, b, c: The general form of a quadratic equation is y=ax2+bx+c. We need to identify the values of a, b, and c in the given equation y=x2−25.
Compare with general form: Comparing y=x2−25 with y=ax2+bx+c, we can see that a=1, b=0, and c=−25. The coefficient b is zero because there is no x term in the given equation.
Find axis of symmetry: The axis of symmetry for a parabola given by y=ax2+bx+c is found using the formula x=−2ab. We will substitute the values of a and b into this formula to find the axis of symmetry.
Substitute values and calculate: Substitute a=1 and b=0 into the formula x=−2ab to find the axis of symmetry.x=−2×10x=0The axis of symmetry for the parabola y=x2−25 is x=0.
