Hello!
The problem given says, for every piece of chicken, it costs $2.25. Firstly, we can assign some variables, y is the total price, and x is the number of chickens bought.
Therefore, the function representing this situation is y = 2.25x.
With that equation, we can substitute the number of chickens into our equation and solve. Remember that y is also f(x).
f(1) = 2.25(1) = 2.25
f(2) = 2.25(2) = 4.5
f(3) = 2.25(3) = 6.75
f(4) = 2.25(4) = 9
f(5) = 2.25(5) = 11.25
For the coordinate plane, vertically (x-axis), for every 5 spaces, there is 1 piece of chicken, and horizontally (y-axis), for every 2 spaces, there is 1 dollar (or every 1 space, there is 0.50 cents).
I have posted the graph and the table of values. Remember that x is the pieces of chicken, and y is total price on the coordinate plane and the table of values.
