Answer 1

Answer:

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

Step-by-step 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:

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

To find c, we plug in x=8,

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

$c = 23$
