Polynomials
A name for a polynomial with three terms
What is a trinomial?
The inverse operation of a power
What is a root?
A special right triangle whose sides are in the proportion a:a:a√2
What is a 45-45-90 triangle?
f-1(x) is a shorthand for this
What is the inverse function of x?
This property states that x=x, and is often used as a reason when a quantity equals itself.
What is the reflexive property of equality?
x4+3x2 is a ____ degree ___nomial.
What is a fourth degree binomial?
Another way of expressing √3 (hint: with a power)
31/2
This trigonometric ratio uses the opposite and adjacent legs of a right triangle from a given reference angle.
What is the tangent ratio?
The graph of a quadratic function is called this.
What is a parabola?
This property allows you to say that if a=b, then b=a.
What is the symmetric property of equality?
x2-25 is an example of this special product.
What is the difference of squares?
x5/x3 = x2 is an example of this law of exponents in action.
What is the quotient rule?
A special right triangle whose sides are in the proportion a:2a:a√3
What is a 30-60-90 triangle?
The lowest point of a function's graph is called this.
What is a minimum?
This property justifies the step from “If a=b and b=c, then a=c.”
What is the transitive property of equality?
x2+10x+25 is an example of this special product.
What is a perfect square trinomial?
(x5)3 = x15 is an example of this law of exponents in action.
What is the power of a power rule?
This trigonometric ratio uses the opposite leg of a right triangle from a given reference angle and the hypotenuse.
What is the sine ratio?
As x approaches infinity, f(x) approaches infinity. This is a way of describing the ____ behavior of a function.
What is end behavior?
This property of equality lets you add the same quantity to both sides of an equation without changing the solution.
What is the addition property of equality?
In standard form, the terms of a polynomial are written in this order.
What is descending order?
This law of exponents explains why (an)(am)=an+m
What is the product of powers rule?
This point of concurrency is found at the intersection of a triangle’s altitudes.
What is an orthocenter?
This type of function has no breaks, jumps, or holes in its graph and can be drawn without lifting your pencil.
What is a continuous function?
This property allows you to replace a variable or expression with an equivalent one in a proof or equation.
What is the substitution property?
