Given f(x) = x + 7 and g(x) = x-3, what is f(x) + g(x)?
2x + 4
10x
2x –7
-2x + 10 this should be better

What is the difference between the points (4, 7) and (4, -5)? a. 0 units b. 2 units c. 4 units d. 12 units

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) .

The table represents a function f(x). what is f(3)? a.-9 b.-1 c.1 d.9
