Across
- 3. a line in the cordinate plane that separated the solutions of the inequality from the nonsolutions. Points on line may or may not be solutions.
- 4. change made to function y=af(x-h) + k at a, h, or k. Four types are dilations, reflections, rotations, and translations
- 6. Part of the quadratic formula that equals the square root ofb^2. Its value determines the number of real roots in the equation.
- 12. equation An equation where the unknown is in the variable. Solve it by taking the logarithm of each side of the equation.
- 13. an expression consisting of the sum of one or more terms. which each is the product of a constant and a variable raised to an integer power
- 14. set of points in a coordinate plane. they are on one side of the boundary of the graph of a linear inequality
- 15. inverse reciprocal of any nonzero number. product of reciprocals is 1, the multiplicative identity.
Down
- 1. indicates the strength of the correlation, r. The closer r is to 1 or -1, the more closely the data resembles a line and the more accurate your model is likely to be
- 2. The point at which the parabola intersects the axis of symmetry. The y value of the vertex represents the maximum or minimum value of the function.
- 5. value function a function that contains an algebraic expression within absolute value symbols. f(x) = |x| is the parent graph
- 7. used on graph of a relation to determine if relation is a function. If a function, vertical line will not pass through more than one point
- 8. lines that do not intersect and have the same slope. referring to graphing
- 9. number any number of the form a + bi, where a and be are real numbers. b is not equal to zero, and I is the square root of -1
- 10. inverse of any nonzero number. the product of reciprocals is 1, multiplicative identity. A is 1/A
- 11. if f is the name of a function, f(x) shows the function. ."f of x" or "function of x". Also range value f(x) for domain value x.
