Answer:
-16
Step-by-step explanation:
3*5=15
3*8=24
15-24= -9
-9-7=-16

Actually Welcome to the Concept of the Inverse of real function.
Let's consider here, g(n) = y ,
so we get as,
![y = \sqrt[3]{ \frac{n - 1}{2} }](https://tex.z-dn.net/?f=y%20%3D%20%20%5Csqrt%5B3%5D%7B%20%5Cfrac%7Bn%20-%201%7D%7B2%7D%20%7D%20)
no, cubing the power both side we get as,
=>

now,

so finally, we get as,
=>

hence,here, n = inverse of the g(n) function.
so,
g^-1 (n) = 2y^3+1.
Where are the graphs??? How’re we supposed to send you the answers?
