How do I solve 12a?

The answer in the textbook is 1.5 and -1.

c ) f ( x ) = -8 ( x ) = - = ( - 3x ) Neil wants to sketch d ) f ( x ) = 1x1, 8 ( x ) = 1 -2x1, b (x ) = * ? How can Neil 11. The function y = f(x) has been transformed to y = f(kx) . Determine the EXAMPLE 1 value of k for each transformation. Sketch the graph a) a horizontal stretch by the factor 4 the transformed a horizontal compression by the factor a reflection in the y-axis Neil's Soluti d) a horizontal compression by the factor ; and a reflection in the y-axis The parent fu A quadratic function has equation f(x) = x - x - 6. Determine the Vertica x-intercepts for each function. factor a ) y = f(2x) b ) y = f ( * * ) c ) y = f ( - 3x) 13. a) Describe how the graph of y = f(kx) can be obtained from the graph of U y = f(x). Include examples that show how the transformations vary with Reflecti the value of k. the x-ax b) Compare the graph of y = f(kx) with the graph of y = kf(x) for different values of k and different functions f(x) . How are the transformations alike? How are they different? tending
