To find the direct variation a letter in this equation must be isolated(a=kx)

What is k?

100

The way for classifying a polynomial like x3-4

What is by the number of terms of the polynomial and degree of the variable? in this case it as cubic binomial.

100

For a function f(x)= x-3 with x= 2,4,7,8 describe how to find the domain and range and what they are for this function.

What is the, domain is found by inputting range which are the x values(2,4,7,8) to find y values which what f(x) is equal to, which is y=-1,1,4,5?

100

To create a graph of a linear equation you must find two of these.

What are the coordinates of two points on the line?

200

In an inverse variation, as the x value increases, the y value does this?

What is decreases?

200

This is how to factor a polynomial like 15x3+9x2+21x.

What is you break each part to find the greatest common factor and simplify? using the example: (3-5-x-x-x+3-3-x-x+3-7-x) the GCF is 3x. The simplified version is 5x2+3x+7.
200

This type of function is a single unbroken line.

What is continuous function?

When given a system of equations, a graph can be made by created these lists of values.

What are tables of x and y coordinates for each of the equations?

300

This method of solving for a 3x3 matrix where you separate the matrix into three 2x2 matrices is known by this name.

What is expansion by minors?

300
The FOIL method for multiplying polynomials involves these steps.

What is multiplying the first terms, multiplying the outside terms, multiplying the inside terms, and multiplying the last terms?

300

This function is made of a bunch of isolated points.

What is discrete function?

To graph with intercepts, on must input what values into the equation?

What is a zero for the x value to find the y intercept and a zero for the y value to find the x intercept?

This polynomial (x2-9) is a type thathas a special factoring pattern known as the difference of two squares that tells it is the product of what two polynomials.

What is (x+3)(x-3)?

400

To multiply three binomials these basic steps must be followed.

What is use the foil method with two of the binomials to create a trinomial then multiply the remaining binomial against the trinomial.

Solving systems of two equations and two variables(like 4x-8y=2, and y=9+2x) using the substitution method involves these steps.

What is isolate one of the variables(y=9+2x) and take what it is equal to(9+2x) and insert it in the same variable in the other equation(4x-8(9+x)=2) and simplify?
