Unit 4: Modeling Polynomial Functions
Across
- 8. A polynomial can have constants (like 4), variables (like x or y) and exponents (like the 2 in y2), that can be combined using addition, subtraction, multiplication and division
- 11. A polynomial can have constants (like 4), variables (like x or y) and exponents (like the 2 in y2), that can be combined using addition, subtraction, multiplication and division, but: no division by a variable., a variable's exponents can only be 0,1,2,3,... etc., not an infinite number of terms.
- 12. if the curve 'bends' downward.
- 13. if the value of y increases on increasing the value of x
- 14. The smallest value taken by the function.
- 16. the order in which two numbers are added/multiplied does not change the solution..
- 17. Expression A polynomial with two terms.
- 19. a function whose value decreases as the independent variable increases over a given range.
- 20. the coefficient of the term of highest degree in a given polynomial.
- 21. multiplying a number by a group of numbers added together is the same as doing each multiplication separately.
- 22. The function: f(x) = a^x
- 24. describes the behavior of the graph of the function at the "ends" of the x-axis. In other words, the end behavior of a function describes the trend of the graph if we look to the right end of the x-axis (as x approaches +β ) and to the left end of the x-axis (as x approaches ββ ).
- 25. We define nth root of any number as the number which when taken to nth power results in the original number,
- 26. the number of times a solution appears in the multiset
Down
- 1. Any of the 4 areas made when we divide up a plane by an x and y axis, as shown.
- 2. The largest exponent the variable has in a polynomial with one variable.
- 3. A number with two components, a real number component and an imaginary number component. Complex numbers are written in the form π + ππ, where π is the real part and ππ, is the imaginary part.
- 4. exponents that are fractions, where the numerator is a power and the denominator is a root.
- 5. A value we get closer and closer to, but never quite reach
- 6. A symbol written above and to the right of a mathematical expression to indicate the how many times the mathematical expression (base) should be multiplied by itself.
- 7. Where the highest exponent of the variable (usually "x") is a square (^2).
- 9. how the numbers in an addition/multiplication problem are grouped doesnβt change the solution.
- 10. the number with an equal real part and an imaginary part equal in magnitude but opposite in sign
- 15. Where lines cross over each other (solution) (where they have a common point).
- 18. The largest value taken by the function.
- 23. if the curve 'bends' upward
