Question

Use the graph of y = -x2 - 2x + 3 to solve
the equation -x2 - 2x + 3 = 0. What are
the solutions?

Answer 1

Explanation:
y
+
2
x
=
3

y
=
−
2
x
+
3

When
x
=
0
, y-intercept
=
3
coordinates
(
0
,
3
)

When
y
=
0
, x-intercept
=
3
2
coordinates
(
3
2
,
0
)

Knowing two points, we can draw the graph.
graph{-2x + 3 [-10, 10, -5, 5]}
