20. Use the piecewise function to evaluate points f(-1), f(2), and f(12).
O A. f(-1) = 3, f(2) = 1, and f(12) = 41
B. f(-1) = 3, f(2) = 6, and f(12) = 41
O C. f(-1) = 2. f(2) = 1, and |(12) = 41
D. f(-1) = 2. f(2) = 6, and f(12) = 41

Step-by-step explanation:

Given

The piece wise function can be split to:-

Required

f(-1), f(2) and f(12)

To solve for each of these functions, we first check the range they fall into, then we execute the corresponding function

-1 is within the range of

Hence; we make use of  

Substitute -1 for x

2 is within the range of

Hence; we make use of  

Substitute 2 for x

12 is within the range of

Hence; we make use of  

Substitute 12 for x

ok
