Question

For the life of me I can't rememeber how to solve 3(1/2)^x. If I will show you how I would do it. Then can someone please explain what part I did wrong?

Answer 1

So.

Answer 2

I would obviously start off by plugging in numbers for x.

Answer 3

such as -1 - 1 and 2

Answer 4

-1, 0, 1, 2 *

Answer 5

have you been told what the value of x is?

Answer 6

No.

Answer 7

I was told to graph it.

Answer 8

You can't solve it unless it's equal to something, or like stephchen said, if you knew \(x\).

Answer 9

well. Iwas plugging in numbers for x.

Answer 10

Oh, I see your second part now.

You can graph it, sure.

Answer 11

if you're asked to graph it you don't have to find x

Answer 13

Wel. it makes it easier because then you have an x and y value. so you can easily graphmultiple points.

Answer 14

Right. But graphing and solving are very different. If you wanted to solve the equation, as you originally said, you would need an equal sign (e.g., \(3 (\frac{1}{2})^{x} = 0\)).

Answer 15

Good point..
