Exploring Function Notation Concepts

What is the purpose of replacing y with f(x) in function notation?

• To give the function a name

• To simplify the equation

• To perform multiplication

• To make the equation more complex

How should f(x) be read?

• f times x

• f divided by x

• f of x

• f plus x

What is the function notation for the equation y = 8x - 5?

• k(x) = 8x - 5

• h(x) = 8x - 5

• g(x) = 8x - 5

• f(x) = 8x - 5

If f(x) = x^2 + x, what is f(4)?

• 24

• 20

• 16

• 28

If g(x) = 8x - 5, what is g(4)?

• 37

• 35

• 32

• 27

What is the first step in evaluating f(x) when given a specific value for x?

• Replace x with the given value

• Simplify the equation

• Multiply all terms by x

• Add the given value to x

When evaluating f(x) with a more complex expression, what should you do first?

• Add the expression to x

• Square the expression

• Multiply the expression by x

• Replace x with the expression

If f(x) = x^2 + x, what is f(x - 3)?

• x^2 - 6x + 6

• x^2 - 6x + 9

• x^2 - 5x + 6

• x^2 - 3x + 9

What is the result of squaring (x - 3)?

• x^2 - 3x + 9

• x^2 - 6x + 9

• x^2 + 9

• x^2 - 9
