Answer:
x > 4; r–1(x) = 4 + StartRoot StartFraction 11 Over x EndFraction EndRoot
Step-by-step explanation:
We are given that
We have to find the domain of restriction on r(x) and corresponding inverse function.
Let
Now, replace x by y and y by x then, we get
The function is not defined at x=4
But,
The inverse function defines for all positive real values.
Therefore, domain of r(x)=x>4 and inverse function
Option:
x > 4; r–1(x) = 4 + StartRoot StartFraction 11 Over x EndFraction EndRoot

Answer:
Maggie did not apply the law correctly
Step-by-step explanation:
Given 3 numbers A, B and C, for a commutative property
(A+B)+C = C+(A+B)
This shows that the remains the same no matter what values comes first
For the given expression
4/5+6.9y-8 = 6.9y+8-4.5
The values are not commutative because of the presence of negative sign. For the expression to be commutative, they must be equal no matter the way it is arranged and the sign must be positive all through for both sides. Hence Maggie did not apply the law correctly
