Which of these is a set of inputs and outputs for the function f(x) = 2x + 4? A
(1, 2), (2, 5), (3, 8)
B
(1, 4), (2, 6), (3, 7)
C
(1, 5), (1, 8), (1, 10)
D
(1, 6), (2, 8), (3, 10)

wrong/ point thirsty answers will be deleted.

D

Step-by-step explanation:

2(1) + 4 = 6

2(2) + 4 = 8

2(3) + 4 = 10

D. (1, 6), (2, 8), (3, 10)

Step-by-step explanation:

f(x) = 2x + 4

(1, 6)

x = 1

output = 6

f(1)

f(1) = 2(1) + 4 = 6

(2, 8)

x = 2

output = 8

f(2)

f(2) = 2(2) + 4 = 8

(3, 10)

x = 3

output = 10

f(3)

f(3) = 2(3) + 4 = 10

so, the answer is D. (1, 6), (2, 8), (3, 10)

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80
