U might need to use Desmos.
1. Find f(2), Find f(-7), find f(3a).
2. Show me where on the graph is f(x)=10, Using the graph find f(x) when x= -6.
3. Determine if f(x) is a function or not and explain why or why not. Find which intervals f(x) is increasing and decreasing and explain why?
Find where the local f(x) has a local minimum and where f(x) has a local maximum.
4. If g(x)=3x, find g(f(x)), if g(x)= -2x, find f(g(-1))
5. Will the graph of f inverse be a function? Why or why not?
