• 3
• -1

Given f(x) =
2x² + 5x - 17, find f(-1). 

• f(-1) = -20
• f(-1) = -24

Given f(x) = -4x - 10 and f(x) = 10. Find x

• x = -5
• x = 5
• x = -50
• x = 30

How do you read f(x)?

• f x

• f of x

• f parenthesis x

• f with an x inside parenthesis

If a question asks you to find f(2), what does that mean?

• Let x = 2
