Answer:

Step-by-step explanation:

Piecewise functions have different definitions, depending on when you evaluate them.
Given an input x, your function returns:
- 2x if the input is negative
- 1 if the input lies between 0 (included) and 2 (excluded)
- the square root of x if the input is greater than 2 (included)
You want to know what f(0) is. In other words, you want to know what happens if we give 0 as input.
The piecewise definition tells us that, if the input is 0, the function outputs 1.
So, you have f(0) = 1.
It would be 50
130+180= 310
360-310= 50
You get 180 from the missing side by 70 that becomes 180.
8 sandwiches cut into 4 pieces each gives you 32 pieces.
32 pieces divided into 2 plates equals 16 on each plate.
8×4 = 32
32/2=16
