Graphs with restricted(forbidden) regions!

From this information, we can complete the sketch Note that the graph is symmetrical about the y-axis, so the point (0, 9) is a local minimum point.

Step 4: Complete the sketch We can also complete the part of the graph to the left of the asymptote, remembering that the graph does not cut the x-axis.

Pg 8 in notes

4y y - 7  0 Solvingy >  or < -3 

This means that there is a restricted region as there are no y values between -3  and . This then gives us the T.P`s. y max = -3  y min =  This graph crosses the horizontal asymptote
