Exponental law

so
√(81y^5)=√81 times √(y^5)
√81=9 or -9
√(y^5)=y^2 times√y
answer is 9y^2 times √y or -9y^2 times √y
Refrection of a function across the y-axis, changes the sign of x in the function.
Thus, given the function:

Refrection of the function across the y-axis will result in the function:

Refrecting a function across the x-axis, changes the sign of the function.
Thus, refrecting the function:

across the x-axis will result in the function:

The graph of

and

is attached.
The green curve represents the graph of the function

, while the orange curve represents the graph of the function

.
Answer:

Hope this helped
Ans_ It is Sandwich Theorem..
Answer:
For Q. 17 I believe it's "the function has a minimum at -1" take this answer with a grain of salt but the other three seem to be true and I don't know how to solve this one so I'm assuming it's the false one.
