3. Perform the following transformations to the function y = x . In each case, write the formula the gives the requested transformation and draw the graph of the transformed function. 1) a horizontal expansion by a factor of 4. 2) a horizontal compression by a factor of 1 3) a vertical expansion by a factor of 4. 4) a vertical compression by a factor of 1/4. 4. Find the function formula giving function notation. Describe the transformations that would the graph of the second function from the graph of the first function. 1) f(x) = /x1 - g(x) = 5f(x)+7 2 ) f ( x ) = x2 -> g (x) =f(=x+2)-4
