PLEASE HELP I WILL LITERALLY CASHAPP YOU IF YOU CAN ANSWER THIS CORRECTLY THIS IS NOT A JOKE
weqwewe [10]

Answer:

f(x) = 5x - 30

Yes it is a function

Step-by-step explanation:

Because when you input 0 you get -30 we know it starts at 0 or (0,-30). This gives us b in the equation y = mx + b.

We know that for every 4 cars washed it increases by 20. So 20/4 is 5. This tells us m = 5.

Plug it all in and you get  y = 5x - 30 or f(x) = 5x - 30
