Question
Evaluate the following piecewise function for x = 0 and x = 5
- (-1 , 0) and (-8 , 5)
- (0 , -1) and (5 , 8)
- (1 , 0) and (8 , 5)
- (0 , 1) and (5 , -8)
Hint:
We simply put in the values of x's to get the values of f(x). According to this, we get the perfect pairs.
The correct answer is: (0 , 1) and (5 , -8)
Step 1 of 1:
For x = 0, f(x) = x + 1 = 0 + 1 = 1. So, the pair is (0, 1)
For x = 5, f(x) = -x – 3 = -5 – 3 = -8. So, the pair is (5, -8)
Final Answer:
The right choice is- b. (0, 1) and (5, -8)
