Find f(x) when x = 4 Subtitute the x with 4 in the function f(x) = 3x + 2 f(4) = 3(4) + 2 f(4) = 12 + 2 f(4) = 14 The value of f(x) when x = 4 is 14
Find f(x) when x = -1 Subtitute the x with -1 in the function f(x) = 3x + 2 f(-1) = 3(-1) + 2 f(-1) = -3 + 2 f(-1) = 1 The value of f(x) when x = -1 is 1
