Question
The piecewise-defined function f(x) is shown.
f(x) = x + 2 , x ≤ 0
f(x) = 4x , x > 0
What is f(−3)?
- 12
- 5
- -1
- -12
Hint:
We simply put in the values of x to get the value of f(x).
The correct answer is: -1
Step 1 of 1:
For x = -3 (≤0), f(x) = x + 2 = -3 + 2 = -1
So, f(-3) = -1
Final Answer:
The right choice is- c. -1
