Across
- 3. function: a function that serves to “undo” another function.
- 7. a transformation that pulls the points of a graph horizontally away from the y-axis of vertically away from the x-axis.
- 8. a curve formed by the intersection of a cone with a plane parallel to a straight line in its surface
- 9. division: used when a polynomial is to be divided by a linear expression and the leading coefficient (first number) must be a 1.
- 11. notation: y=f(x) defines a function named f.
- 12. of a function: the set of all possible inputs for the function.
- 13. a measure of its steepness, is calculated as "rise over run".
- 16. the square: writing a quadratic in the form of a squared bracket and adding a constant if necessary.
Down
- 1. a straight line associated with a curve such that as a point moves along an infinite branch of the curve
- 2. arithmetic: algebraic expressions that consist of variables and coefficients.
- 4. method: the algebraic method to solve simultaneous linear equations.
- 5. variation: a type of proportionality in which one quantity directly varies with respect to a change in another quantity, by the same factor.7. composition: an operation where two functions say f and g generate a new function say h in such a way that h(x) = g(f(x)).
- 6. the exponent or power to which a base must be raised to yield a given number5. intercept form: one of the forms used to calculate the equation of a straight line, given the slope of the line and intercept it forms with the y-axis.
- 10. differences: any of a sequence of differences obtained by incrementing successively the dependent variable of a function by a fixed amount.
- 12. the part of the quadratic formula underneath the square root symbol: b²-4ac.
- 14. a mathematical expression consisting of two terms connected by a plus sign or minus sign.
- 15. value: the non-negative value of x without regard to its sign.
- 16. conjugates: keeps the same real part of the complex number but changes the sign of the imaginary part.
