Option A. is correct for the given condition.

Lets solve it through steps of range and functions,

First of all, Solve the equation:
f(x) = |x|+5
= > x = -5 (1)

= > x = 5 (2)

So these would be the ranges of X in between 5 and -5.

Hence option A. R{f(x)eR  [f(x) < 5} is correct.

X+3, -2x^(2)-6x, 4x^(3)+12x^(2) what is the 8th term in this geometric sequence
seraphim [82]

Answer:

  a8 = -128x^8 -384x^7

Step-by-step explanation:

The formula for the general term of a geometric sequence with first term a1 and common ratio r is ...

  an = a1·r^(n-1)

Here, we have a1 = (x+3) and r = (-2x^2-6x)/(x+3) = -2x. Then the 8th term is ...

  a8 = (x+3)(-2x)^(8-1)

  a8 = -128x^8 -384x^7
