Quadratics
This value determines the number of real solutions a quadratic equation has and is found under the square root in the quadratic formula.
What is the discriminant?
This is a set of two or more equations containing the same variables.
What is a system of equations?
This is the steepness of a line, often represented by the letter ‘m’
What is slope?
This is the general shape of the graph of an exponential function, either increasing rapidly or decreasing towards zero.
What is a curve?
This is the distance around a two-dimensional shape.
What is perimeter?
This is the name for the highest or lowest point on the graph of a quadratic function, representing either a maximum or minimum value.
What is the vertex?
This method of solving systems involves solving one equation for one variable and substituting that expression into the other equation.
What is substitution?
This is the point where a line crosses the y-axis.
What is the y-intercept?
In the exponential function y = abx, this value represents the initial amount or starting value.
What is ‘a’?
This is the amount of space inside a two-dimensional shape, measured in square units.
What is area?
These are the x-values where a quadratic function intersects the x-axis; they can be found by setting the function equal to zero and solving.
What are the roots, zeros, or x-intercepts?
This method of solving systems involves adding or subtracting the equations to eliminate one of the variables.
What is elimination (or addition)?
This is the form of a linear equation written as y = mx + b.
What is slope-intercept form?
This occurs when the value of ‘b’ in the exponential function y = abx is greater than 1.
What is exponential growth?
This theorem relates the lengths of the sides of a right triangle.
What is the Pythagorean Theorem?
This method of solving quadratic equations involves rewriting the equation in the form (x + a)² = b, then taking the square root of both sides.
What is completing the square?
This is the term for a system of equations that has no solution.
What is inconsistent?
Lines that have the same slope are said to be this.
What are parallel?
This occurs when the value of ‘b’ in the exponential function y = abx is between 0 and 1.
What is exponential decay?
These are two angles whose measures add up to 90 degrees.
What are complementary angles?
This is the name given to the U-shaped curve that represents the graph of a quadratic function.
What is a parabola?
If two lines in a system of equations have the same slope and the same y-intercept, the system has this many solutions.
What is infinitely many?
Lines that intersect at a right angle are said to be this, and their slopes are negative reciprocals of each other.
What are perpendicular?
This is a horizontal line that the graph of an exponential function approaches but never touches.
What is an asymptote?
This is the name for a three-dimensional figure with two parallel, congruent bases and rectangular lateral faces.
What is a prism?
