Answer with explanation:
Price of Product on the Website = $ 412.50
It is given that, product is offered at a discount of 25% on the website.
Let actual price of product on the store = $ x
Writing the above statement in terms of equation
→Price at store - Discount= Price at Website
![x-\frac{25\times x}{100}=412.50\\\\ \frac{75 x}{100}=412.50\\\\x=\frac{41250}{75}\\\\x=550](https://tex.z-dn.net/?f=x-%5Cfrac%7B25%5Ctimes%20x%7D%7B100%7D%3D412.50%5C%5C%5C%5C%20%5Cfrac%7B75%20x%7D%7B100%7D%3D412.50%5C%5C%5C%5Cx%3D%5Cfrac%7B41250%7D%7B75%7D%5C%5C%5C%5Cx%3D550)
Price at store of that Product = $ 550

Step-by-step explanation:
I
don't
know
see you in next question
Since f(x) is (strictly) increasing, we know that it is one-to-one and has an inverse f^(-1)(x). Then we can apply the inverse function theorem. Suppose f(a) = b and a = f^(-1)(b). By definition of inverse function, we have
f^(-1)(f(x)) = x
Differentiating with the chain rule gives
(f^(-1))'(f(x)) f'(x) = 1
so that
(f^(-1))'(f(x)) = 1/f'(x)
Let x = a; then
(f^(-1))'(f(a)) = 1/f'(a)
(f^(-1))'(b) = 1/f'(a)
In particular, we take a = 2 and b = 7; then
(f^(-1))'(7) = 1/f'(2) = 1/5
