I’m not 100% sure this is correct, because I’ve never done these before, but try 12, this is the answer I got from a reliable app that I usually use
Answer:
Hence the answer is given as follows,
Step-by-step explanation:
Graph of y = f(x) given,
(a) 
(b) 
(c) 
(d) 
(e) 
(f) 
{ Hole in graph}
Hence solved.
The only type of symmetry is
vertical line of symmetry
Answer:
D) The third side could be 4 meters long.
Step-by-step explanation:
The third side of a triangle must be greater than the difference and less than the sum of the other two sides.
5-4=1
5+4=9
So the third side must be GREATER THAN 1 and LESS THAN 9. (1<x<9)
Therefore, the answer can't be A or C. The second one <em>could </em>be correct, depending on how much less than 4 it is. But the last one is definitely correct.
