Determine whether the data set could represent a quadratic function. X: -8 -4 0 4 8
Y: 5 11 14 14 11

Mary beth used the mapping rule to find the coordinates of a point that had been rotated 90° counterclockwise around the origin. examine the steps to determine whether she made an error. m (3, –6) is rotated 90° counterclockwise. (x, y) → (–y, x) 1. switch the x- and y-coordinates: (6, –3) 2. multiply the new x-coordinate by –1: (6(–1), –3) 3. simplify: (–6, –3) .

F(n + 1) = f(n) – 8. if f(1) = 100, what is f(6)?

What is the slope of the line shown below?
