Question

consider the function f(x) = 3 x - 9?

Answer 1

Answers:

a. 0

b. 19

Step-by-step explanation:

a.

$f(x) = 3x - 9, \; x = 3$

$f(3) = 3*3 - 9 = 9 - 9 = 0$

b.

$3x - 9 = 48$

$3x = 57$

$x = 19$

Answer 2

• Answer:

A, 0; B, 19

Step-by-step explanation:

A.

Substitute in the 3 for X

F(3)= 3(3)-9

F(3)= 9-9

F(3)=0

B.

3x-9=48

  +9  +9

3x=57

57/3= 19

3/3=1

19=x
