Answer:
No, I don't think so.
Step-by-step explanation:
I don't think this is a function because the triangle is made of multiple points. Some of these points share the same <em>x</em> point, so this concludes that a triangle on a graph is not a function.
Hope it helps!
Answer: Option C

Step-by-step explanation:
Whenever we have a main function f(x) and we want to transform the graph of f(x) by moving it vertically then we apply the transformation:

If
then the graph of k(x) will be the graph of f(x) displaced vertically b units down.
If
then the graph of k(x) will be the graph of f(x) displaced vertically b units upwards.
In this case we have

We know that this function has its vertex in point (0,0).
Then, to move its vertex 7 units down we apply the transformation:
.
Then the function k(x) that will have its vertex 7 units below f(x) is

16 times 4 equals to 64. 64 is simply 4 sets of 16 added together.
Other factors of 64 include, 1,2,4,8,16,32, and 64.
