Quadratic Function Notes

	f(x) = a(x − h)² + k, a ≠ 0 vertex = (h, k) axis of symmetry: x = h a > 0 → concave up a < 0 → concave down h > 0 → h units to the right h < 0 → \|h\| units to the left k > 0 → k units up k < 0 → \|k\| units down
	f(x) = ax² + bx + c Vertex To solve for x - intercept : let f(x) = 0 and solve for x To solve for f(x)-intercept: let x = 0 and solve for f(x) Quadratic Formula :
