This is the derivitive of x
critical points are where the first derivitive is equal to 0 or where the derivitive doesn't exist
ok, it is 0 at x=0 and 2
so I is true but not II
the point of inflection is where the slope of the 1st derivitive=0
that is at x=1
so III is true
I and III
4th option
Lets assume the number be x so by the problem 2x -5 is the answer.
Step-by-step explanation:
4k - 6 < 3k + (k - 1)
4k < 3k + 6(k - 1)
4k < 3k + 6k - 6
4k < 9k - 6
4k - 9k < -6
-5k < -6
k < <u>-</u><u>6</u>
-5
k < <u>6</u>
5
