Answer:
The correct option is 1. The axis of symmetry of the given graph is x=1.
Step-by-step explanation:
If a quadratic function is defined as
... (1)
then, the axis of symmetry is

The given parabolic equation is
.... (2)
On comparing (1) and (2), we get

The axis of symmetry of given graph is



Therefore the axis of symmetry of the given graph is x=1 and option 1 is correct.
Answer:
I think that's false but im confused
We can always do a prime factoring of it, and check
50 = 2*5*5
2*5²
a perfect square, so-called, is the resulting number of a squared value, well 50 is not the result of anything squared, is the result of 3 factors, in this case 2,5 and 5.
a perfect square will be something like say 64, or 144, because
64 = 8*8
8²
144 = 12*12
12²
AB= 3x+4 + 5x-6 = 8x-2
the others are just what they are given as
Well she started with P. She then found 87 ADDING that to her original P meaning she has P+87 coins :)
