Answer:
see explanation
Explanation:
Given
y = x² + 2x + 1
To find the zeros let y = 0, that is
x² + 2x + 1 = 0 ← x² + 2x + 1 is a perfect square
(x + 1)² = 0
x + 1 = 0 ( subtract 1 from both sides )
x = - 1 with multiplicity 2 ← zero
This indicates that the graph has a minimum turning point at (- 1, 0)
Note from your table
the value for x = - 1 should be y = 0 ( not - 2 )
