COMPLEX NUMBERS AND EXPRESSIONS

Activities, Examples, or Resources

AII.CNE.1: Know there is an imaginary number, i, such that i^2 = -1, and every complex number can be written in the form a + bi, with a and b real.  Use the relation i^2 = –1 and the commutative, associative, and distributive properties to add, subtract, and multiply complex numbers.

Complex Number Operations

AII.CNE.2: Translate expressions between radical and exponent form and simplify them using the laws of exponents.

AII.CNE.3: Understand that rational expressions form a system analogous to the rational numbers, closed under addition, subtraction, multiplication, and division by a nonzero rational expression; add, subtract, multiply, and divide algebraic rational expressions.

AII.CNE.4: Rewrite algebraic rational expressions in equivalent forms (e.g., using laws of exponents and factoring techniques).

AII.CNE.5: Rewrite rational expressions in different forms; write a(x)/b(x) in the form q(x) + r(x)/b(x), where a(x), b(x), q(x), and r(x) are polynomials with the degree of r(x) less than the degree of b(x), using long division and synthetic division.

AII.CNE.6: Find partial sums of arithmetic and geometric series and represent them using sigma notation.

FUNCTIONS

Activities, Examples, or Resources

AII.F.1: Determine whether a relation represented by a table, graph, or equation is a function.

AII.F.2: Understand composition of functions and combine functions by composition.

AII.F.3: Understand that an inverse function can be obtained by expressing the dependent variable of one function as the independent variable of another, as f and g are inverse functions if and only if f(x)=y and g(y)=x, for all values of x in the domain of f and all values of y in the domain of g.  Find the inverse of a function that has an inverse.

AII.F.4: Understand that if the graph of a function contains a point (a, b), then the graph of the inverse relation of the function contains the point (b, a); the inverse is a reflection over the line y = x.

AII.F.5: Describe the effect on the graph of f(x) by replacing f(x) with f(x) + k, k f(x), f(kx), and f(x + k) for specific values of k (both positive and negative) with and without technology.  Find the value of k given the graph of f(x) and the graph of f(x) + k, k f(x), f(kx), or f(x + k).
