Question

If anyone that actually understands, could help, would be much appreciated

Answer 1

a. -1

b. 1

c. 6

Step-by-step explanation: f(any value) just means plug in the value given inside of the f and see what y value comes out. for the first on, go to where four it on the x-axis and you will see that the y-value is -1. Repeat the same thing for f(0) where you can look directly on the y-axis and get 1 as the answer. Lastly, look where -4 meets the y-axis and it will be 6.
