Let f(x) = 1/x
Evaluate and plot g(x)= -f(2x) + 1
Start with the innermost transformation and work outward in steps. There are 3 transformations
Wasn't sure how to graph this, or set it up
Hello,
Well, try this :
- 2x
- f(2x)=1/(2x)
- +1 (it's like translating the graph to the upward as you add 1 to each ordinate)
These are 3 transformations. I dunno if you're asked to show all the steps, but as you know the graph for x and the general behave of 1/x, you should be able to make it.
Woops, i forgot the - sign...
Yes, - means that it's reflected across the x-axis.
Then 1/2 means that you divide the ordinates by 2. So it'll give the points at middle way from -1/x and the x-axis. (En gros, tu prends les points à mi-distance entre la courbe -1/x que tu as tracée et l'axe des abscisses, puisqu'à chaque fois tu prends la moitié de l'ordonnée d'un point)
+1 is up 1 yes (puisqu'on ajoute 1 à l'ordonnée de chaque point, c'est comme si on faisait monter la courbe d'une unité)
I hope you really speak French...even in French i'm not sure to be clear :s
