Answer:
f(x) and g(x) are inverse functions
Step-by-step explanation:
In the two functions f(x) and g(x) if, f(g(x)) = g(f(x)) = x, then
f(x) and g(x) are inverse functions
Let us use this rule to solve the question
∵ f(x) = 3x²
∵ g(x) = ![\sqrt{\frac{x}{3}}](https://tex.z-dn.net/?f=%5Csqrt%7B%5Cfrac%7Bx%7D%7B3%7D%7D)
→ Find f(g(x)) by substitute x in f(x) by g(x)
∴ f(g(x)) = 3(
)²
→ Cancel the square root with power 2
∴ f(g(x)) = 3(
)
→ Cancel the 3 up with the 3 down
∴ f(g(x)) = x
→ Find g(f(x)) by substitute x in g(x) by f(x)
∴ g(f(x)) = ![\sqrt{\frac{3x^{2}}{3}}](https://tex.z-dn.net/?f=%5Csqrt%7B%5Cfrac%7B3x%5E%7B2%7D%7D%7B3%7D%7D)
→ Cancel the 3 up with the 3 down
∴ g(f(x)) = ![\sqrt{x^{2}}](https://tex.z-dn.net/?f=%5Csqrt%7Bx%5E%7B2%7D%7D)
→ Cancel the square root with power 2
∴ g(f(x)) = x
∵ f(g(x)) = g(f(x)) = x
→ By using the rule above
∴ f(x) and g(x) are inverse functions
Answer:
The profits for firma A and B will decrease.
Step-by-step explanation:
Oligopoly by definition "is a market structure with a small number of firms, none of which can keep the others from having significant influence. The concentration ratio measures the market share of the largest firms".
If the costs remain the same for both companies and both firms decrease the prices then we will have a decrease of profits, we can see this on the figure attached.
We have an equilibrium price (let's assume X) and when we decrease a price and we have the same level of output the area below the curve would be lower and then we will have less profits for both companies.
Answer: 9
