Final answer:
The equation of the axis of symmetry for the parabola y = x² – 7x + 13 is x = 7 / 2, using the formula x = -b / (2a).
Step-by-step explanation:
To find the equation of the axis of symmetry for the parabola defined by the equation y = x² – 7x + 13, we can use the formula for the axis of symmetry for a parabola in standard form, y = ax² + bx + c, which is x = -b / (2a). Here, 'a' is the coefficient of the x² term and 'b' is the coefficient of the x term.
In the given equation, a = 1 and b = -7. Plugging these values into the formula, we get:
x = -(-7) / (2 · 1)
x = 7 / 2
Hence, the equation of the axis of symmetry is x = 7 / 2.
