Which of the following equations correctly describes the function in the table using function notation?

(1 point)

O f(x) =- 4x -5

O f(x) =- 5x -4

O f(y) =- 4x - 5

O f(y) =- 5x -4

Answer 1

f(x) = -4x - 5

Reason: each step in x increases by 1 while f(x) decreases by 4, so slope = -4, and f(0) = -5 gives the y-intercept -5.
