Answer:
Step-by-step explanation:
Common ratio r = a₂/a₁ = 16/(-4) = -4
a₄ = a₃(-4) = 256
a₅ = a₄(-4) = -1024
a₆ = a₅(-4) = 4096
There are specific values of denominators that would yield a non-terminating decimal expansion. In other words, the decimal would be repeating. These denominators are multiples of 3. That could be 3, 6, 9, 12, 15, 18, 21, and so on and so forth. For example, 1/3 = 0.333333, 1/6 = 0.166666, 1/9 = 0.1111, and so on and so forth.
Answer:
f (
x
) −
1 =
(
1/
4 x
) −
2.
Step-by-step explanation:
For inverse function, the x and y interchanges and then make y the subject again of the equation. See the working out below:
f (
x
) = 4
x + 8
f (
x
) = y
y = 4
x + 8
x = 4
y +
8 ----- interchanging y and x
Now make y the subject of the equation:
x = 4
y + 8
−
4
y = -
x + 8
y = (
−
1/
4 )
. − x
+ (
−
1/
4 ) .8
y = (
1/
4 x
) −
2
So the inverse function is:
f (x) −
1 = (
1/
4 x
) −
2
The answer may be y= 1/4 x -3/4
