Question

Part 1:
Solve each of the quadratic equations below and describe what the solution(s) represent to the graph of each. Show your work
•y = x2 + 3x + 2
•y = x2 + 2x + 1
Part 2:
Using complete sentences, answer the following questions about the two quadratic equations above.
•Do the two quadratic equations have anything in common? If so, what?
•What makes y = x2 + 3x + 2 different from y = x2 + 2x + 1?

Answer 1

•y = x2 + 3x + 2
y=(x +2)(x+1)
when y = 0 then x = -2, x = -1
(-2, 0) and (-1, 0)

Answer 2

ok
That makes sense

Answer 3

y = x2 + 2x + 1
y = (x + 1)(x+1)
when y = 0 x = -1
(-1, 0)

Answer 4

graph 1 when x = 0 then y = 2
graph 2 when x = 0 then y = 1

Answer 5

sketch the 2 graphs on the same axis
describe the transformation
