AP Precalculus Unit 1 Review

An even function is symmetric over the y-axis, meaning that for an even function f, it holds that f(-x) = f(x).

An odd function is symmetric about the origin, meaning that for an odd function g, it holds that g(-x) = -g(x).

f(3) = 19.

The correct factored form is (x-6)(x-2)(x+5i)(x-5i).

You analyze the intervals where the graph of f(x) is above the x-axis.

An inflection point is where a graph changes concavity.

The least possible value of n is 5.

Complex roots occur in conjugate pairs, and their presence affects the degree of the polynomial.

You can use factoring, synthetic division, or the quadratic formula for quadratic polynomials.

A function is increasing on an interval if, for any two points x1 and x2 in that interval, if x1 < x2, then f(x1) < f(x2).
