Question

Evaluate the function f(x) = |1 - 3x| for f(-2).
1) 5
2) 7
3) 6
4) 4

Answer 1

To find f(-2) for the function f(x) = |1 - 3x|, the value of x is substituted with -2 resulting in f(-2) = 7.

This correct answer is 2)

Step-by-step explanation:

The student has asked to evaluate the function f(x) = |1 - 3x| for f(-2). To solve this, we substitute x with -2:

• f(-2) = |1 - 3(-2)|
• f(-2) = |1 + 6|
• f(-2) = |7|
• f(-2) = 7

Since the absolute value of 7 is 7, the answer is 7.

This correct answer is 2)
