Name: Date: Class#: Guided Notes What is Function Notation? We all mean . f(x) is a synonym for the same! . fx) is read . f is the of the V=x+7 function, not a variable. f(x) =x2+7 Examples Rewrite using function notation: 1. y = 6x2 2. 7 + x =y You Try! Rewrite using function notation: 1. y = 7x2 - 1 2. x2 - 3 =y Evaluating using Function Notation Evaluate y = - 3x2 + 1 for x = 2. Find f(2) when f(x) = - 3x2 + 1. Evaluate. Let f(x) = x2 +4 and g(x) = x2 + 4x +9 1 . f (3 ) 2 . 8(-4) 3. f (-2) - 8(-1) 4 . f ( -1 ) . 8(0 ) 21
