Question

The graph of y=4^x-1 shifts the graph of y=4^x _______ .

A. left 1 unit
B. right 1 unit
C. up 1 unit
D. down 1 unit

Answer 1

I think D. o-o I can't be sure cuz I've never seen a question asked liek this about a graph

Answer 2

Is it \(y = 4^x - 1\) or \(y = 4^{x-1} \) compared to \(y = 4^x\) ?
Each of those is a proper question and will have a different answer.

Answer 3

If it is \(y = 4^{x - 1} \) compared to \(y = 4^x\), then when you replace x with x - k, the graph shifts k units to the right if k is positive and k units to the left if k is negative.

Answer 4

If it is \(y = 4^x - 1 \) compared to \(y = 4^x\), then it's the same as \(y + 1 = 4^x\).
When you replace y with y - k, the graph shifts k units up if k is positive and k units down if k is negative.
