Answer:
Find the value and the area, of x and y.
To find the x- and y-intercepts of the graph of the function:
y
=
f
(
x
)
=
√
x
2
−
16
x
−
intercept:
y
=
0
:
y
=
f
(
x
)
=
√
x
2
−
16
=

x
2
−
16
=

x
2
=

x
=
±

y
−
intercept:
x
=
0
:
⟹
y
=
f
(
0
)
=
√
0
−
16
=
0
⟹
y
=
√
−
16
=
(imaginary quantity)
Hence, there is no intercept on
y
−
axis
Thus, only the
x
−
intercepts:
x
