Answer:
We want the values of
x
that give a
y
value greater than 0.
Step-by-step explanation:
Let's say that
f
(
x
)
=
x
2
−
10
The graph below shows
y
=
f
(
x
)
:
graph{x^2-10 [-6, 6, -15, 15]}
When we want
f
(
x
)
>
0
, we want
y
>
0
, or all the values of
x
where
f
(
x
)
>
0
.
In this instance,
x
2
−
10
>
0
x
2
>
10
x
>
√
10
x
