The graph of which function has an axis of symmetry at x = 3? f(x) = x2 3x 1 f(x) = x2 – 3x – 3 f(x) = x2 6x 3 f(x) = x2 – 6x – 1

For this case, the function that has an axis of symmetry is given by:

To verify this, what we must do is to derive the function, because the axis of symmetry passes through the minimum or maximum point of the function.

We have then:

From here, we equate the function to zero:

Then, we clear the value of x.

We have then:

A function that has an axis of symmetry at x = 3 is:

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %  

step-by-step explanation:

i believe the correct answer is option 4.principalities were small territories that were run by russian rulers.

which statement correctly defines principalities in northern asia in the 1200s? principalities were small territories that were run by russian rulers.

hope i could ! : )
