4. If 8 (f (x))=2 where f (x) =x+1 and 8(x)=3x -19, determine the value of x. Use the following information to answer the next three questions. Cassandra is given two functions: f (x) =-6x +x and 8 (x) =x+4 5. Determine and simplify f (8 (x)). 6. Graph f (8(x)) using technology. . State the domain and range of f (8 (x)). 8. If g(x) = x' and h(x) = 2x -10, sketch the graph of "(8(x)) by applying transformations to g (x)=x . Describe the transformations
