The document discusses continuity of functions. A function is continuous at a point c if the limit of the function as x approaches c exists and equals the value of the function at c. Polynomial and rational functions are continuous everywhere in their domains. A function can have discontinuities where it is not defined or where the limit does not equal the function value. Discontinuities are either removable, where redefining the function can make it continuous, or non-removable, where an asymptote prevents continuity. A function is continuous on a closed interval if it is continuous on the interior and the one-sided limits equal the function values at the endpoints.
To graph the combination of functions h(x) = (f + g)x, add the y-values of f(x) and g(x) at each x, and multiply the sum by x. The domain of h(x) is the intersection of the domains of f(x) and g(x), and the range is all real numbers since adding and multiplying real numbers results in real numbers.
Matrix multiplication involves multiplying matrices according to certain rules. A matrix is a rectangular layout of numbers arranged in rows and columns. To multiply matrices, each element in a row of the first matrix is multiplied by the corresponding element in a column of the second matrix and those products are summed to form the element of the product matrix in that row and column. Matrix multiplication is useful in many fields including business, data analysis, geology, and robotics.

Polynomial functions are described by their degree and have certain characteristics. The graph of a polynomial is smooth and continuous without sharp corners. Odd degree polynomials rise on the left and fall on the right, while even degree polynomials rise on both sides. The number of x-intercepts and local maxima/minima are limited by the degree. Polynomials can be matched based on their degree, leading coefficient, even/odd nature, and number of x-intercepts and local extrema. The x-intercepts of a polynomial correspond to the roots of the equation, and a repeated root indicates a zero of higher multiplicity which affects the graph.

Synthetic division is a method for dividing a polynomial by a linear factor such as (x - a). The coefficients of the polynomial are written in a column. The divisor is written above the column. Working from right to left, each term of the divisor is multiplied by the coefficient above and subtracted from the number above. The result is the quotient and remainder of dividing the polynomial by the linear factor.
A polynomial function contains terms of variables raised to whole number powers that are added or subtracted. Examples of polynomials are x^2 + 5x + 3 and 3x^4 - 2x^3 + x^2 - 4.
