Answer:
Step-by-step explanation:
p(x) = |x|
in : R let : y = |x|
calculate : x
y² = |x| ²
y² = x²
y² - x²= ( y - x)( y +x) by identity
y = x or y = - x
the inverse : y = x or y = - x
conclusion : the inverse is : g(x) = |x|
Answer:
The nth term of the geometric sequence 7, 14, 28, ... is:
Step-by-step explanation:
Given the geometric sequence
7, 14, 28, ...
We know that a geometric sequence has a constant ratio 'r' and is defined by
where a₁ is the first term and r is the common ratio
Computing the ratios of all the adjacent terms
The ratio of all the adjacent terms is the same and equal to
now substituting r = 2 and a₁ = 7 in the nth term
Therefore, the nth term of the geometric sequence 7, 14, 28, ... is:
0.4x 0.4x 0.4 = (0.4)^3
Exponential form = (0.4)^3
