Function Rules

Rule: x n = n(n-1)/2 + 1. Sequence: 1, 2, 4, 7, 11, 16, 22, (That rule looks a bit complicated, but it works) Solution 2: After 1 and 2, add the two previous numbers, plus 1: Rule: x n = x n-1 + x n-2

How do you find the function rule? + Example

f (x) = a (x – (–1)) 2 + 3 = a (x + 1) 2 + 3. Now we only need to find a . So, we plug in the x and y values from P (–5, – 7) since, if P is on the curve, its coordinates must satisfy the rule , so f (x)

Algebra Examples

When we add +2 to x variable (f(x)=(x+2)^2), base graph will shift -2 units on the x-axis. (In x^2 y was 0 when x was 0. But in (x+2)^2, y is 0 when x is -2) Finally, the graph is
