Points of inflections are zeroes of the second derivative. We have:

So, the second derivative equals zero if and only if

So, this is the only point of inflection of this function.
Answer:
1.
is a perfect square trinomial
Step-by-step explanation:
2. Perfect square trinomials are algebraic expressions with three terms that are created by multiplying a binomial to itself.
3. I will upload a picture showing my work
Answer: -2
(-5)(-1)x=(10)(-1)
5x = -10
x = -2
6x-3-9x-2
6x-9x = -3x
-3-2 = -5
the the equation is: -3x-5
