### Vocabulary Words

TermDefinition
linear function An equation that makes a straight line when it is graphed
first definition represents a linear function of the form y=mx+b
second difference represents a quadractic function of the form y=ax*bx+c
quadratic function A quadratic function is a second-degree polynomial function of the form , where a, b, and c are real numbers
exponential function function whose value is a constant raised to the power of the argument, especially the function where the constant is e.
common ratio The common ratio is the ratio between two numbers in a geometric sequence
rate of change The speed at which a variable changes over a specific period of time.
y-intercept they can have at most one y-intercept. Analogously, an x-intercept is a point where the graph of a function or relation intersects with the x-axis.
initial value is an ordinary differential equation together with a specified value, called the initial condition,
slope This form of a line's equation is called the slope-intercept form, because b can be interpreted as the y-intercept of the line, that is, the y-coordinate where the line intersects the y-axis.
slope intercept form The slope-intercept form is simply the way of writing the equation of a line so that the slope (steepness) and y-intercept (where the line crosses the vertical y-axis) are immediately apparent. Often, this form is called ' y = mx + b' form.
point slope form the equation of a straight line in the form y − y1 = m(x − x1) where m is the slope of the line and (x1, y1) are the coordinates of a given point on the line — compare slope-intercept form.
inequality difference in size, degree, circumstances, etc.; lack of equality. "social inequality"
compound inequalities A compound inequality is a combination of two or more inequalities joined by either an 'and' or an 'or
absolute value equations The absolute value of a number may be thought of as its distance from zero. Generalisations of the absolute value for real numbers occur in a wide variety of mathematical settings
absolute value inequalities an inequality that has a variable within an absolute value symbol
properties of equality The property that states that if you add the same number to both sides of an equation, the sides remain equal
exponential inequalities exponential inequalities. An inequality with variables in the exponent is called an Exponential Inequality.
quadratic inequalities A quadratic inequality is a function whose degree is 2 and where the y is not always exactly equal to the function
graphing standard form The graph of the equation has x-intercept a and y-intercept b. The intercept form is in standard form with A/C = 1/a and B/C = 1/b.
