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. 3. Determine and simplify f (8(x)). 6. Graph f(g(x)) using technology. 7. State the domain and range of f (8 (x)). 8. If g(x)= x' and h(x) =2x -10, sketch the graph of "(g(x)) by applying transformations to 8 (x)=x . Describe the transformations
