This problem wants us to write a quadratic function, f, whose zeros are negative 11 and 3.
00:06
And to begin writing this, what we're going to do is write it in factored form first, because if we're given 0s a negative 11 and 3, those zeros have to come from setting a binomial equal to 0 and getting that solution.
00:19
So, negative 11 would come from a binomial of x plus 11.
00:23
If we set that equal to 0 and then subtract 11, that's what would give us our 0 of negative 11.
00:28
And we'll do the same thing for positive 3.
00:30
That would come from a binomial of x minus 3 said equal to 0.
00:34
So right now we do have our function, but that's in factored form...
