Answer:
Explanation:
1). f(x) = 2x 
 f(-3) = 2(-3) = -6
 f(1) = 2(1) = 2
 f(4) = 2(4) = 8
 Ordered pairs → (-3, -6), (1, 2), (4, 8)
2). f(x) = 2x + 1 
 f(-3) = 2(-3) + 1 = -5
 f(1) = 2(1) + 1 = 3
 f(4) = 2(4) + 1 = 9
 Ordered pairs → (-3, -5), (1, 3) and (4, 9)
 x -3 1 4 
 f(x) -5 3 9
3). f(x) = -3x 
 f(-3) = -3(-3) = 9
 f(1) = -3(1) = -3
 f(4) = -3(4) = -12
 Ordered pairs → (-3, 9), (1, -3), (4, -12)
 x -3 1 4
 f(x) 9 -3 -12
