Removed. I made a mistake haha and someone made the correct one :)
Answer:
For the given square root, two closest perfect square are are 0 and 1 and their square roots are 0 and 1 respectively.
Step-by-step explanation:

Hence, the two nearest square roots of the given square root are 0 and 1
For checking :

And, clearly 0.45 lies between 0 and 1
⇒ √0 < √0.2 < √1
⇒ 0 < 0.45 < 1
Hence, For the given square root, two closest perfect square are are 0 and 1 and their square roots are 0 and 1 respectively.
Answer:
c²(1 + 3d)
Step-by-step explanation:
The sum of square of c and d is;
c² + d
Twice the product of c and d is;
2c²d
Because c² + d is increased by 2c²d the algebraic expression becomes;
c² + d + 2c²d
or
c²(1 + 3d)
An inverse of the function is when you switch the variables around, or solve for f(x). I'm going to make f(x) y, because it is just the same thing. So y=4x. Divide by 4, so x=y/4. Then you can switch the variables so y is on the outside, or the dependent variable, and the answer is y=x/4, or y=1/4x.
Let's choose a specific point/vertex on both parallelogram and see the changes;
Observing that A is (-4, 1) and A' is (4, -1).
From this we can observe that the graph was flipped over the x-axis because the x value went from negative to positive. Again, we see that the shape was flipped over the y-axis since the y values went from positive to negative.
From this scenario, the correct solution should be A.
Double check this by picking another vertex and comparing.
D's coordinates are (-2, 1) and D' is (2, -1)
Again, the x and the y values are flipped, meaning that this graph was flipped over the x-axis and y-axis, confirming our answer.
Hope I helped :)
