- 2. / also sometimes called a root, of a real-, complex- or generally vector-valued function f is a member x of the domain of f such that f(x) vanishes at x; that is, x is a solution of the equation f(x) = 0.
- 4. / are exactly the x-intercepts of the quadratic function , that is the intersection between the graph of the quadratic function with the x-axis.
- 6. / The number of times the radicand is multiplied by itself.
- 9. / a numerical or constant quantity placed before and multiplying the variable in an algebraic expression (e.g., 4 in 4x y).
- 10. function / is one of the form f(x) = ax2 + bx + c, where a, b, and c are numbers with a not equal to zero.
- 11. / consisting of three terms.
- 12. 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.
- 13. formula /is the solution of the quadratic equation.
- 16. / the value of a function at a certain point in its domain, which is greater than or equal to the values at all other points in the immediate vicinity of the point.
- 17. / is the peak in the curve as shown on the right
Down
- 1. / is the locus of points such that the distance to the focus equals the distance to the directrix.
- 3. root / of a number is a value that, when multiplied by itself, gives the number.
- 5. / are where the graph crosses the x-axis.
- 7. / a function of the coefficients of a polynomial equation whose value gives information about the roots of the polynomial.
- 8. / is a binomial formed by negating the second term of a binomial.
- 14. of symmetry / The two sides of a graph on either side.
- 15. number / is a number of the form a + bi, where a and b are real numbers and i is the imaginary unit, satisfying i2 = −1.
- 16. / value of a function is the place where the graph has a vertex at its lowest point.
