    Answer:

    f(x) = 50 + 25(x – 1)

    Step-by-step explanation:

    Let’s write an equation to represent the function that will allow Damon to calculate the cost of his video game membership service:

    Lifetime membership fee = $ 50

    First video game is free

    Then any video game purchased after = $ 25.

    Let x to represent the total cost of the video game membership service, in consequence we can write the equation this way:

    f(x) = 50 + 25(x – 1)

    • If x = 1, then f(1) = 50 + 0 = 50
    • If x = 2, then f(2) = 50 + 25 = 75
    • If x = 5, then f(5) = 50 + 100 = 150
