Across
- 3. A mathematical expressions that has a coefficient and/or a variable part.
- 5. Finding a curve that best fits a scatter plot. Three types of regression are linear, quadratic, and exponential.
- 6. A polynomial with only two terms.
- 9. The roots of an equation are the values that solve the equation.
- 15. equation in which the highest power in a variable is a 2.
- 16. The sum of one or more monomials. Each term of the polynomial has the form ax^n.
- 17. The average of the numbers in a data set. Calculate the mean by adding all the numbers and dividing the total by the number of numbers in the set.
- 19. A list of numbers that usually has some kind of pattern
- 22. The middle. Umber in a data set after it has been arranged from least to greatest. If there are an even number of numbers in the data set, the median is found by adding the two middle numbers and dividing by 2.
- 23. The location where a curve crosses the x-axis. The y-coordinate of the x-intercept is 0.
- 24. The set of values that can be output from a function is the range of that function.
- 25. A graphical way of representing a data set where each piece of data is represented with a dot.
Down
- 1. Numbers and variables that are combined with the operations of math.
- 2. The polynomials that evenly divide into a polynomial.
- 4. A translation of a graph is when the points on it are each shifted the same amount in the same direction.
- 7. The numbers that can be input into a function. The domain is the set of x coordinates in a function.
- 8. A “U” shaped curve that is the graph of the solution set of a quadratic equation .
- 10. A number multiplied by a variable expression. in the expression 5x+2, 5 is the coefficient of x.
- 11. The location where a curve crosses the y-axis. The x-coordinate of the y intercept is 0. In slope-intercept form, y=mx+b, the y intercept is located at (0,b)
- 12. The turning point of a parabola is its vertex. If the parabola opens upward, the vertex is the minimum point. If the parabola opens down-ward, the vertex is the maximum point.
- 13. A letter, often an x, y, or z, that represents a value in a mathematical expression. In an algebraic equation, the variable is often the unknown that needs to be solved for.
- 14. The most frequent number in a data set.
- 18. Two mathematical expressions with an equals sign between them. 3x+2=8
- 19. The slope of a line is a measure of the line’s steepness. The equation for the slope of a line that passes through the two points (x1,y1)and(x2,y2)is m=((y2-y1)/(x2-x1)
- 20. Something that takes numbers as inputs and outputs numbers. Functions are often labeled with the letters f or g. The notation f(2)=7 means that when the number 2 is input into function f, it outputs the number 7.
- 21. The number being raised to a power in an exponential expression.
