Answer: -4
Explanation:
When a question says f(0), this means that the function is being evaluated at the point x = 0. For this problem in specific, the function f(x) is defined as a piecewise function, which means you will have to use the 3 different pieces depending on the value of 'x' you are dealing with.
For this problem, x = 0. This means that the third piecewise function must be used. I hope you can understand what I'm trying to explain. You use the different piecewise functions depending on the 'x' value.
Okay so let's use the third piecewise function:
