HELP FOR BRAINLIEST AND FAT POINTS PIECEWISE FUNCTION

Find where your inputs make sense.
For the first problem it asks to find the input of f(1), the second constraint would be correct because 1 is less than for 4 and negative 2. Then you would plug in your values.
So -3(1)=-3
The second one fits the constraints of the first so plug it in for 2x-3. You would get 2(-4)-3, which equals -11
For the last one find what value corresponds to the input value of 6 and then plug it in.
6/6 -1 =0
Hope this helped you understand.
