Algebra 2

3. A function that repeatedly multiplies an initial amount by the same positive number. You can model all exponential functions using y=abx, where a is a nonzero constant, b>0, and b≠1.
5. A function is a relation in which each element of the domain corresponds with exactly one element in the range.
7. A monomial or the sum or difference of two or more monomials. A quotient with a variable in the denominator is not a polynomial.
8. The absolute value of a real number, x, written |x|, is its distance from zero on the number line.
9. A matrix is a rectangular array of numbers written within brackets.
10. A quadratic function is a function that you can write in the form f(x)=ax2+bx+c, where a≠0.

1. A logarithmic function is the inverse of an exponential function.
2. A function that contains the independent variable in the radicand.
4. Complex numbers are the real numbers and the imaginary numbers.
6. If function f pairs a value b with a, then its inverse, denoted f−1, pairs the value a with b. If f−1 is also a function, then f and f−1 are inverse functions.
