The table represents the function f (x) = 3x-1

x, f(x)
-5, a
-2, -7
4, b
8, c
Use the drop-downs to choose the values of a, b, and, c to complete the table.

Answer:

a=-16, b=11, c=23

Explanation:

The function that represents the table is


f(x) = 3x - 1

We substitute x=-5 to find the value of a.


a = f( - 5) = 3( - 5) - 1

We evaluate to obtain:


a = - 15 - 1 = - 16

To find the value of b, we substitute x=4,

We get:


b = f(4) = 3 * 4 - 1 \\ b = 12 - 1 \\ b = 11

To find c, we plug in x=8,


c = f(8) = 3(8) - 1 \\ c = 24 - 1


c = 23
