Which function has a vertex at (2, -9)? * fx) = -(x - 3)2
Of(x) = (x + 8)2
O fx) = (x - 5)(x + 1)
O f(x) = -(x - 1)(x - 5)

He letter p on the number line below represents the number . (use the hyphen for negative numbers and write answer as a decimal, such as –7.2) number line from negative 7 to positive 7 in increments of 0.5 is shown. only the whole numbers are labeled. a point labeled p is placed at the eleventh tick mark to the left of 0.
