plz mark brianliest answer
Step-by-step explanation:
When we draw graph of
y
=
x
2
−
2
x
−
1
,
as a point on
x
-axis means
y
=
0
,
intercepts on
x
-axis, give the solution of equation
x
2
−
2
x
−
1
=
0
Now, if
x
=
2
,
y
=
−
1
if
x
=
0
,
y
=
−
1
if
x
=
−
2
,
y
=
7
if
x
=
1
,
y
=
−
2
if
x
=
3
,
y
=
2
and if
x
=
−
3
,
y
=
14
So joining points
{
(
2
,
−
1
)
,
(
0
,
−
1
)
,
(
−
2
,
7
)
,
(
1
,
−
2
)
,
(
3
,
2
)
,
(
−
3
,
14
)
}
we get the graph
graph{x^2-2x-1 [-10, 10, -5, 5]}
It shows that intercepts on
x
-axis are
−
1
2
and
2
1
2
