Kara creates the table shown to represent the function ƒ(x) = x2 + 2x - 3.
determine the zero(s) of the function.

Factor completely. 4p^2 + 36p + 81 express the answer in the form (ap + b)^2

Use the quadratic function to predict f(x) if x equals 8. f(x) = 25x2 − 28x + 585

There are two major tests of readiness for college: the act and the sat. act scores are reported on a scale from 1 to 36. the distribution of act scores in recent years has been roughly normal with mean µ = 20.9 and standard deviation s = 4.8. sat scores are reported on a scale from 400 to 1600. sat scores have been roughly normal with mean µ = 1026 and standard deviation s = 209. reports on a student's act or sat usually give the percentile as well as the actual score. the percentile is just the cumulative proportion stated as a percent: the percent of all scores that were lower than this one. tanya scores 1260 on the sat. what is her percentile (± 1)?
