Definitions
This point on a graph can be identified by plugging in x=0.
What is a y-intercept?
Solve 3x-1=5x+5
What is x=-3?
This feature of a linear equation tells us the rate of change of y per unit increase in x
What is slope?
The name of this form: y=ax2+bx+c
What is standard form?
This type of function is made up of two or more parts.
What is a piecewise function?
This is the set of all possible inputs for a relation.
What is domain?
Solve l 2x+1 l = 5
What are x=2 and x=-3?
This function form is y=m(x-x1)+y1
What is point-slope form?
This term is defined as the square root of negative one.
What is i ?
This test is a visual way to determine whether or not a graph is a function by seeing if there are multiple intersections at any given input value.
What is the vertical line test?
This point, on absolute value and quadratic functions, is also the maximum or minimum point, depending on if the graph opens up or down.
What is the vertex?
Solve l x-1 l > -2
What are all real numbers?
When two lines have negative reciprocal slopes and intersect to create four 90 degree angles.
What is perpendicular?
This line goes through the vertex and divides the graph into two equal parts
What is the axis of symmetry?
The type of problem whose solution is represented by the intersection (or overlap) of areas.
What is a system of inequalities?
This term is used to change denominators with radical or imaginary terms to a real number denominator.
(3-2i) and (3+2i) are an example of this
What are conjugates?
Solve 2x2 + 3x - 5 = 0
What are x=1 and x=-5/2 ?
When I have any absolute value expression set to be less than any negative number, this is the solution set.
What is no solution?
This general form of a quadratic function is the only one that cannot always be written with real numbers. When it is, two of the constants tell us about the function's roots.
What is factored/intercept form?
This notation is used to indicate that the edge point of a piecewise function is not included in its graph.
What is an open circle?
This expression is part of the quadratic formula, and tells us the number and type of solutions.
Solve 3(x-1)2+27=0
what is x=1+/- 3i?
In the function y=-3 l x-1 l +7, the "7" does this transformation to the parent function y= lxl.
What is shift up vertically 7 units?
The name of the formula derived by completing the square on a quadratic function in standard form, then solving for the roots.
What is the quadratic formula?
This rectangular arrangement of numbers can be used to represent the coefficients and constants of a system of linear equations
What is a matrix?
