Answer:
means the inverse function
= ![\sqrt[3]{(x + 6)/5}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B%28x%20%2B%206%29%2F5%7D)
Step-by-step explanation:
means the inverse function
to find an inverse function, flip the x and y variables and solve for y
f(x) = 5x^3 - 6
y = 5x^3 - 6
x = 5y^3 - 6
x + 6 = 5y^3
(x + 6)/5 = y^3
= y
A. The common ratio is 5
B. The sequence is the Fibonacci sequence. There is no common ratio.
C. The sequence is a sequence of squares. There is no common ratio.
D. The common ratio is 1/2.
_____
A and D are geometric sequences.
B and C are not geometric sequences.
The first one is B. This is because both numbers need to be subtracted.
The second one is A. Subtracting a negative number results in a positive.
