Q.
Given
h
(
x
)
=
4
x
−
4
h(x)=4 x-4
h
(
x
)
=
4
x
−
4
, find
h
(
−
5
)
h(-5)
h
(
−
5
)
.
\newline
Answer:
Substitute
x
x
x
with
−
5
-5
−
5
:
To find the value of
h
(
−
5
)
h(-5)
h
(
−
5
)
, we need to substitute
x
x
x
with
−
5
-5
−
5
in the function
h
(
x
)
=
4
x
−
4
h(x) = 4x - 4
h
(
x
)
=
4
x
−
4
.
\newline
h
(
−
5
)
=
4
(
−
5
)
−
4
h(-5) = 4(-5) - 4
h
(
−
5
)
=
4
(
−
5
)
−
4
Perform multiplication and subtraction:
Now, we perform the multiplication and subtraction.
\newline
h
(
−
5
)
=
(
4
×
−
5
)
−
4
h(-5) = (4 \times -5) - 4
h
(
−
5
)
=
(
4
×
−
5
)
−
4
\newline
h
(
−
5
)
=
−
20
−
4
h(-5) = -20 - 4
h
(
−
5
)
=
−
20
−
4
Add the numbers together:
Finally, we add the two numbers together to get the final result.
\newline
h
(
−
5
)
=
−
20
−
4
h(-5) = -20 - 4
h
(
−
5
)
=
−
20
−
4
\newline
h
(
−
5
)
=
−
24
h(-5) = -24
h
(
−
5
)
=
−
24
