Write a function rule for each table.

days

cost to rent a truck

1

34

2

56

3

78

4

100

c = 22d + 12

c = 22d

c = 22d + 22

c = 12d + 22

Step-by-step explanation:

The given table is

Days      Cost to Rent a Truck

   1                        34

   2                       56

   3                       78

   4                       100

To right a function of this expression, we first have to find the ratio of these values and then use the point-slope form to get the equation which is linear, because the table is showing a linear relation.

Now, we take one point and the slope to find the linear function

Therefore, the function has to have a ratio of change of 22 and an y-axis interception at y=12. So, the answer is the first choice, where x is d and y is c.
