7. Graph:
y+=+abs%28x%2B4%29 Notice that y can never be negative because the absolute value of a quantity is never negative. This shows up on the graph below.
The graphs look like:
graph%28400%2C400%2C-10%2C5%2C-5%2C5%2Cabs%28x%2B4%29%29%29
8. Graph:
y+=+abs%28-%281%2F2%29x-3%29 y can never be negative here also. See the second graph.
The graphs look like:
graph%28400%2C400%2C-15%2C5%2C-5%2C5%2Cabs%28-%281%2F2%29x-3%29%29
