Not all rational functions have holes. A rational function is a ratio of two polynomials, and holes occur at points where both the numerator and denominator equal zero, indicating a common factor. If a rational function has no common factors between the numerator and denominator, it will not have any holes, although it may have vertical asymptotes or other features.
You can evaluate functions at points. For example, my pay is a function of how many hours I work. At 5 hours I can evaluate the result.
You find the average rate of change of the function. That gives you the derivative on different points of the graph.
Typically, functions are graphed on x-y coordinates. A function of x means that for every x point, there must be a single y point. You can also many properties by graphing a function, such as the minimum and maximum points, slopes and inflection points, and the inverse of the function (y values plotted on x coordinate, and x values on y coordinate).
The trigonometric functions that do not have real zeros are the cosine function ((\cos(x))) and the secant function ((\sec(x))). The cosine function is never zero for (x) values that correspond to integer multiples of (\frac{\pi}{2}), while the secant function, being the reciprocal of cosine, is undefined at those points. Therefore, both functions do not intersect the x-axis in the real number system.
If you want to compose two functions, you need the range of the first function to have points in common with the _____ of the second function.
range
a function whose magnitude depends on the path followed by the function and on the end points.
There are no points of discontinuity for exponential functions since the domain of the general exponential function consists of all real values!

g(-3) and g(5) are not functions but the values of the function g(x) at the points x = -3 and x = 5.

Non-examples of continuous functions include step functions, which have abrupt jumps or breaks, and piecewise functions that are not defined at certain points. Additionally, functions like the greatest integer function (floor function) are not continuous because they have discontinuities at integer values. These functions fail to meet the criteria of having no breaks, jumps, or holes in their graphs.
A linear function is called "linear" because it represents a straight line. To graph a linear function, find two points that satisify that function, plot them, and then draw a straight line between them.
