1) The red graph (1) is the graph of f(x) = 2x. Describe the transformation of the blue function (2) and write the equation of the graph.
the equation of the red graph can't be f(x) = 2x comparing the blue and red graph red graph move left by 1 unit, move up by 3 units, then flip it upside down. do you know how these transformation will affect the equation?
what do you mean it cant? thats what my assignment says.. are you sure?
f(x) = 2x is actually like this.|dw:1342075920171:dw| ok we can assume the red graph is 2x. do you know what equation will move the red graph to the left 1 unit?
i do not
|dw:1342076064397:dw| ok this is the red graph (just a re-draw)
the red graph in your diagram is e^x. the transformation is a reflection across the x-axis -f(x) and moved 3 units up (+3)
|dw:1342076131376:dw| f(x) = 2(x+1) <-- x + 1 will move the graph to the left by 1
