Question 866568
The text in the image is difficult to read; but you can find Number 17's answer yourself like this:

Take any simple polynomial function or use y=x^3.  Make a simple sketch using just a few points.  Now multiply the right side by -1, so you have y=-y^3, and find a few points for this one and graph them.  NOW, how do the graphs of y=x^3 and y=-x^3 differ?  This is one of the qualities you must learn about graphs of functions.  The negative 1 factor makes reflection through the x axis.
