The graph of which function has an axis of symmetry at x = 3?f(x) = x2 + 3x +1f(x) = x2 -3x - 3f(X) = x2 + 6x + 3f(x) = x2 - 6x - 1
Accepted Solution
A:
f(x) = x² - 6x - 1 To find the axis of symmetry, use the axis of symmetry formula: -b\2a, according to the Quadratic Equation y = Ax² + Bx + C. You understand?
