Transform the function {eq}f(x) = \dfrac{1}{x} {/eq} by (i) shifting the graph 5 units to the left and (ii) shifting the graph 1 unit down. Step 1: Graph the original function. Because we are looking at the parent rational function, it will look like this: ...
Linear functions are similar to linear equations. They are functions that can be represented by a straight line graph. A few examples of linear functions that will give a straight line graph: f(x) = x, f(x) = 2x – 2, f(x) = x + 1 The variables in linear functions have linear ...

The intercepts of a function are the values of x when f(x) = 0 and the value of f(x) when x = 0, corresponding to the coordinate values of x and y where the graph of the function crosses the x- and y-axes. Find the y-intercept of a rational function as you would for any ...

the result will be the liner– 1exceptthatrcannot equal 1, sincer= 1 is not in the domain ofg(r). In the graph, this strange result appears as a "hole," as illustrated below using an open circle atr= 1. Thus, we must treat rational functions carefully with regard to changing...
Rational functions f(x) = 1/x have a domain of x ≠ 0 and a range of x ≠ 0. If you have a more complicated form, like f(x) = 1 / (x – 5), you can find the domain and range with the inverse function or a graph. See: Rational functions. Sine functions and cosine functi...
This function is the sum of the previous two functions. But, while the sum of an odd and an even number is an odd number, I cannot conclude the same of the sum of an odd and an even function. Note that the graph of this function does not have the symmetry of either of the ...
How to Find the Domain of a Function which is Rational? To find the domain of arational function, we just set the denominator not equal to zero. For example, to find the domain of f(x) = 2/(x-3), we set x-3 ≠ 0, by solving this, we get x≠3. So the domain is the set...
