Alissa is analyzing an exponential growth function that has been reflected across the y-axis. she states that the domain of the reflected function will change because the input values will be the opposite sign from the reflected function. simon disagrees with alissa. he states that if an exponential function is reflected across the y-axis, the domain will still be all real numbers. which student is correct and why?

The figure shows triangle def and line segment bc, which is parallel to ef: triangle def has a point b on side de and point c on side df. the line bc is parallel to the line ef. part a: is triangle def similar to triangle dbc? explain using what you know about triangle similarity. part b: which line segment on triangle dbc corresponds to line segment ef? explain your answer. part c: which angle on triangle dbc corresponds to angle f? explain your answer. asap
