Fx) = -3x² + 2x - 7, then f(-1) =​

Given:

The function is

To find:

The value of f(-1).

Solution:

We have,

Putting x=-1, we get

Therefore, the value of f(-1) is -12.

angle addition postulate

2x=56

step-by-step explanation:

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 %
