Question

21. (03.02) If f(x) = x − 4, what does f(3) represent? (1 point) The value of (x − 4) when x = 3 The value of x when (x − 4) = 3 The value of 3f(x) when x = 3 The value of f(x) when (x − 4) = 3

Answer 1

$the \: value \: of \: (x - 4) \: when \: x = 3 \\ \\ since \: f(x) = x - 4 \\ \\ therefore \: \: f(3) = 3 - 4 = - 1........(1) \\ \\ \\ \\ and \: when \: x = 3 \\ \\ then \: x - 4 = 3 - 4 = - 1.......(2) \\ \\ \\ from \: equation \: (1) \: and \: (2) \: \: this \: statement \: is \: true. \\ \\ hope \: it \: helps....$
