Question

Evaluate the function f (x) = -3x + 7 when the domain is {-4, 1,7}

Answer 1

19, 4, - 14

Explanation:

Step 1:

f (x) = - 3x + 7

Step 2:

f (x) = - 3 (- 4) + 7

Step 3:

f (x) = 12 + 7

Step 4:

f (x) = 19

Step 5:

f (x) = - 3 (1) + 7

Step 6:

f (x) = - 3 + 7

Step 7:

f (x) = 4

Step 8:

f (x) = - 3 (7) + 7

Step 9:

f (x) = - 21 + 7

Step 10:

f (x) = - 14

Answer:

19, 4, - 14
