Answer:
Step-by-step explanation:
By definition the domain of an inverse function is the range of f(x) and the range of the inverse function is equal to the domain of the principal function f(x).
If you have a function , then to find the inverse function, follow these steps:
1. Make
2. Solve for the variable "x":
3. Exchange the variable "x" with the variable "y":
4. Exchange "y" with. Then the inverse function is:
The polygon is a perfect square. I graphed those points on a graph. I hope this helped if not let me know so I can try and write the correct answer.
-7 to make 4 so -4x=4 x=-1
The answer is x=-1
Hope this helps:)
You just have to plug in each thing:
So f(0):
3(0)^2 - 4 = -4
so its not A
f(-2) and f(2):
3(-2)^2 - 4
3(2)^2 -4
now we don't even have to calculate these, anything to the power of an even number is a positive number so -2^2 and 2^2 both equal 4
B is correct, so you can do the others if you want to check, but if B is true the others shouldn't be true.
