Question

Which of the following represent the order pairs for the function

f(x) = 3x + 1 if the domain is { 1, 2, 3, 4}

Select one:
a. {(-2, 5), (-1, -2), (0, 1), (1, 4)}
b. {(1,4), (2, 7), (3, 10), ( 4, 13)}
c. {(4,1), ( 7, 2), ( 10,3), (13,4)}
d. none of the above

Answer 1

Answer:

b

Step-by-step explanation:

Given domain is ( 1 2 3 4)

So subsitute each value in the f(x) = 3x+1

x=1 then f(x) = 4

x=2 then f(x) = 7

x=3 then f(x) = 10

x=4 then f(x) = 13

So ordered pairs are (1,4) (2,7) (3,10) (4,13)
