Answer:
x=0.2
Step-by-step explanation:
2/5=0.4
0.4-0.2=0.2
Answer:
Sorry my mistake, it is actually worded as "f(x) =(x+6)^2"
Explanation:
y
=
(
x
+
6
)
2
with
x
≥
−
6
, then
x
+
6
is positive, so
√
y
=
x
+
6
And
x
=
√
y
−
6
for
y
≥
0
So the inverse of
f
is
g
(
x
)
=
√
x
−
6
for
x
≥
0
If the equation has roots of +-3i. The equation would be,
(x + 3i)(x - 3i)
which is equal to x^2 - (3i)^2 = x^2 + 3.
Using division either by synthetic or long method,
(x^3 + x^2 + 9x + 9)/(x^2 + 3)
is equal to,
x + 1 or x = -1
Thus, the answer is the second choice.
