Question

Look at the three functions below. Which of the functions are equivalent? Two of them? None of them? All of them? Show/explain how you

know!
Function 1: x2-x-2
Function 2: (x + 1)(x - 2)
Function 3: (x -0.5)^2 - 2.25​

Answer 1

All of them

Explanation:

x² - x - 2

(x + 1)(x - 2)

x² + x - 2x - 2

x² - x - 2

(x - 0.5)² - 2.25

x² - 2(x)(0.5) + 0.5² - 2.25

x² - x + 0.25 - 2.25

x² - x - 2
