Place the steps to sketch the graph of a rational function in the appropriate order. Sketch the function's graph, plotting additional points as guides as needed.
Choose test numbers to the left and right of each of these places, and find the value of the function at each test number.
Find the function's zeros and vertical asymptotes, and plot them on a number line.
Use test numbers to find where the function is positive and where it is negative.​

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
