We are considering the function 
the graph of this function is the graph of the parent function
after applying the following steps.
1. multiply by -1:
is 
reflected with respect to the x-axis.
2. multiply by 5:
is shrinked towards the y axis.
for example, consider x=1/2
now this means that is "lower" than , which means there is a shrinking of the graph.
3. add 5:
is 
shifted 5 units up.
4.
so the graph of the function a) opens down, b) is shifted 5 units up, c) is not wider than the parent function
Answer: False

Answer: False
Answer:
x = negative 1 plus-or-minus StartRoot 17 EndRoot
Step-by-step explanation:
Given:
We need to solve for x.
First we will solve L.H.S
Factorizing the equation we get;
Now Things which are equal to the same thing are also equal to one another. Since
then, according to the law of transitivity,
Now, applying the Square Root Principle we get:
Now Square root and square gets cancelled.
Since a square root has two values, one positive and the other negative.
Hence Final Answer is .
Answer:
D
Step-by-step explanation:
Start by subtracting 64 from both sides:
Factor this by taking roots. Divide both sides by 25 first:
We "undo" a square by taking the square roots of both sides. Taking the square root leaves the possibilities of both the positive and negative roots of 9. Therefore, the solutions to this are
