By definition the control in a science experiment is a sample that remains the same throughout the experiment. The control must remain the same or equal at all times in order to receive accurate results. You can have as many controls as necessary to achieve results.
Graphs are often an excellent way to display your results. In fact, most good science fair projects have at least one graph. For any type of graph: Generally, you should place your independent variable on the x-axis of your graph and the dependent variable on the y-axis.
Based on the definition of reflection across the y-axis, the graph of y1(x) should look like the graph of f (x), reflected across the y-axis. Take a look at the graphs of f (x) and y1(x). Function (2), g(x), is a cubic function. What would the graph of.
