She keeps the real part and changes the sign of the:Multiplying 2 plus 5i by its own conjugate always produces a number that is:The U-shaped curve produced by graphing a quadratic function is called a:The single extreme point of that curve, its highest or lowest point, is the:A quadratic function is described as a function whose degree is:A parabola with a negative leading coefficient opens downward, so its vertex gives a:Any real number may be substituted into a quadratic, so its domain is all numbers that are:What a graph does as inputs grow very large or very small is called its end:The end behaviour of any polynomial matches that of its term of highest:A point where a graph changes from increasing to decreasing is a:A graph that can be drawn without lifting the pen from the paper is described as:A graph with no sharp corners anywhere along it is described as:A factor appearing three times in a factored polynomial gives that zero a:A graph touches the x-axis at a zero and bounces back. That zero has multiplicity that is:A graph crosses straight through the x-axis at a zero. That zero has multiplicity that is:A polynomial takes a negative value at 3 and a positive value at 4, so between them it must:For a rational zero, numerators come from factors of the constant term and denominators from factors of the:A polynomial with real coefficients has 2 plus 3i as a zero, so it must also have as a zero:A vertical line that a graph rushes towards but never crosses is a vertical:A horizontal line that a graph approaches as inputs grow without bound is a horizontal:A single point where a rational graph is undefined, shown by an open circle, is a hole or removable:A rule counting sign changes to bound the number of positive real zeros belongs to:
