8.3 Extra Practice for Retake #1

Match each Function Equation with its correct Function Notation.

• f(x) = 2x - 6

• h = t²

• h(t) = t²

• y = 2x - 6

• f(x) = 5x

• m = q + 7

• m(q) = x + 7

• y = 5x

• name
• function notation
• output
• variable
• function

f(x) = x³ + 3x² + 1 is the same as f(🌞) = 🌞³ + 3🌞² + 1.

• True

• False

Categorize the functions below.

Groups:

(a) Function Equation

,

(b) Function Notation

• m = 5r + 2

• y = -10x + 7

• d = 55t

• f(x) = 3x

• g(t) = 4t - 12

Select the equations that are written in FUNCTION NOTATION:

• y = −10x + 7

• p(b) = −8b − 4

• f(x) = 2x − 5

• h(c) = 6c + 3

• g(t) = 2t² − 5

How do you read f(x)?

• f x

• f of x

• f parentheses x

• f times x

• y

• x

• input

• an equation
