Function to Table to Graph (linear, quadratic, and absolute value)
How to take an #equation and #graph it using a #table.
To find a "y" value, take the corresponding "x" and replace the x's in the equation with that value. Then do order of operations (PEMDAS). After you've done that for all the x values, you can plot the points on the graph. Just imagine that each row is an ordered pair. If all the dots on the graph are in a straight line, then the #function is linear.
This video could work for #Algebra students who were absent, or in a flipped classroom.
