f(x)= -2(1/2)^x+1
f(x)= -(1/2)^x-3 <-- or A
f(x)= -3(1/2)^x+1
f(x)= -(1/2)^x-1

A student is solving the equation 2^x-1=16^x+2
Step 1: 2^x-1 = 16^x+2
Step 2: 2^x-1 = (2^4)x+2
Step 3: 2^x-1 = 2^4x+8
Which is the next step?


A. x-1= 1(4x+8)

B. x-1= x+2

C. 2(x-1)=4(x+2) <--? or D

D. x-1 =-4x+8

Answer 1

from 2^(x-1) = 2^(4x+8)
you get

x-1 = 4x+8

Your sloppiness with parentheses makes it hard to parse the math correctly.

The other answers are correct. But I have no way to check the graph.
