anonymous 3 years ago 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?

So.

2. anonymous

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

3. anonymous

such as -1 - 1 and 2

4. anonymous

-1, 0, 1, 2 *

5. anonymous

have you been told what the value of x is?

6. anonymous

No.

7. anonymous

I was told to graph it.

8. anonymous

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

9. anonymous

well. Iwas plugging in numbers for x.

10. anonymous

Oh, I see your second part now. You can graph it, sure.

11. anonymous

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

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

14. anonymous

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., $$3 (\frac{1}{2})^{x} = 0$$).

Good point..
