What does it mean to evaluate a function

1 answer:

7 0

To evaluate a function, I do just what I did above: I plug in the given value for x. Here, I am supposed to evaluate at the value x = –3. The notation is different, but "f(–3)" means exactly the same thing as "evaluate at x = –3"! Note how I used parentheses.

Answer:

Step-by-step explanation:

red = 25

green = 25 + 35 = 60

yellow = 15

red = 25/5 = 5

green = 60/5 = 12

yellow = 15/5 = 3

Red + green = 5 + 12 = 17 boxes

yellow = 3 boxes

17 - 3 = 14 boxes

There are 14 more boxes of red and green cars than yellow cars.
