hoe do we graph f(x)= -2/3^x+1 +4
i really dont know how to the reflections .. can someone tell me the points.
I have two thoughts about what this function is supposed to be. Is it
$\displaystyle f(x) = -\frac{2}{3^{x + 1} + 4}$ <-- The red line in the graph below
or
$\displaystyle f(x) = -\frac{2}{3^{x + 1}} + 4$ <-- The blue line in the graph below
I don't know what you mean when you are talking about "reflections." (I'm hoping your version is the blue one...it's easier to tell how to proceed!) The blue graph is a variation on the function $\displaystyle f(x) = a^x$ which has a known shape. So sketch that curve and move it up 4 units. This is a vertical translation. Note that we also have x + 1 in the problem. That is a translation to the left by 1 unit.
Does that help?
