A quadratic function is shown.

f(x) = x² + 8x + 15

What is the factored form of f(x) that reveals the zeros of the function?

• f(x) = (x + 4)(x + 2)

• f(x) = (x + 3)(x + 5)

• f(x) = (x + 2)(x + 6)

• f(x) = (x + 1)(x + 15)

What is the equivalent form of f(x) that reveals the minimum value of the function?

f(x) = x² + 8x + 15

• f(x) = (x + 4)² – 1

• f(x) = (x + 3)²

• f(x) = (x + 2)² + 3

• f(x) = (x + 1)² + 8

• Minimum at (-4,3)

• Maximum at (4,3)

• Maximum at (-4,3)

John charges $2.50 for nachos with cheese and peppers and he charges $2.00 for nachos without peppers. He made 35 sales in one day and earned $80. Create a system of equations and solve to determine how many nachos he sold with peppers and how many without.

• There is not enough information to solve the problem

• He sold 30 nachos with pepper and 5 nachos without peppers

• He sold 20 nachos with peppers and 15 nachos without peppers

• He sold 15 nachos with peppers and 20 nachos without peppers
