1. ## help with graphing

how do you graph this?

y = -2 log base 2 x + 1

I know the negative would make the graph reflect and +1 would move it up one, but I am having some trouble with graphing this equation by plotting it.

Would you convert log base 2, into 2^x and then it would be -2(2^x) x + 1

Hello,

x      log(2)x     *(-2)      +1
