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

Ann [662]

Answer:

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

Step-by-step explanation:

The function whose table is drawn is

$f(x) = 3x - 1$

To find the value of a, we substitute x=-5.

$f( - 5) = 3( - 5) - 1 \\ f( - 5) = - 15 - 1 \\ f( - 5) = - 16$

$\therefore \: a = - 16$

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

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

To find the value of c, we substitute x=8,

$f(8) = 3(8) - 1 \\ f(8) = 24 - 1 \\ f(8) = 23$

$c = 23$
