Answer:
Proved!
Step-by-step explanation:
For two functions f(x) and g(x) to be inverses of each other then;
f(g(x)) = x and g(f(x)) = x condition must be satisfied.
<u>Checking: A. f(x) = 7x³ + 10 and g(x) = ∛</u>
<u />
<u />
So f(g(x)) = 7(![\sqrt[3]{(x- 10)/7}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B%28x-%2010%29%2F7%7D)
)³ + 10
We get; 7() + 10 = x - 10 + 10 = x (*<em>This is correct!)</em>
<em />
So g(f(x)) = ![\sqrt[3]{((7x^3 + 10) - 10)/7}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B%28%287x%5E3%20%2B%2010%29%20-%2010%29%2F7%7D)
Ten cancels out and we are left with;
![\sqrt[3]{7x^3/7}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B7x%5E3%2F7%7D)
= ![\sqrt[3]{x^3}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bx%5E3%7D)
= x (* <em>This is also correct!)</em>
