ANSWER
First choice
EXPLANATION
The graph of f(x) and
are symmetric about the line y=x.
This means that the graph of
is the reflection of f(x) in the line y=x.
This explains why the composition of a function and its inverse yields x, as the result.
The first choice is correct.
The absolute value, or modulus, of a number is its distance from zero, or essentially its magnitude.
The absolute value produces a positive answer.
We have this definition for the absolute value, taking into account its different values for different signs:
Thus, for
, we split the absolute value as such:
and 
We solve each case.
and 
We check these solutions.

Answer:
Step-by-step explanation:
we have to move 5 in the other side with a different sign, to get a 2 grade ecuation
now we know
a=2
b=9
c=-5
we have to find delta
and now we have to use the formula to find the root square
