Lets get started :)
f(x) =

- 2
y =

- 2
This is the original equation, and now we have to find the inverse.
When finding the inverse, just flip the variables, x as y and y as x
f ⁻¹(x)
↓
x =

- 2
We have to isolate y as it is our f ⁻¹(x)
Take 2 to the other side { When you see subtraction, you do addition }
x + 2 =

Take 9 to the other side { When you see division, you do multiplication }
9 ( x + 2 ) = y
9x + 18 = y
f ⁻¹ (x) = 9x + 18
Answer:
The answer would be 5/6.
Step-by-step explanation:
Answer:
x+=(y)=x
Step-by-step explanation:
Rational number is the number that can be made into a ratio. The opposite would be irrational number. When you found a square root number, try to make it ratio then solve it. In this case,
0.25= 1/4
√0.25= √(1/4) = 1/2
√0.33=√(1/3)= irrational
The example would be √4 which can become 2 is rational, but √0.33 can't be solved so it is an irrational number
