## marissa98 Group Title 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? one year ago one year ago

So.

2. marissa98 Group Title

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

3. marissa98 Group Title

such as -1 - 1 and 2

4. marissa98 Group Title

-1, 0, 1, 2 *

5. Stephchen Group Title

have you been told what the value of x is?

6. marissa98 Group Title

No.

7. marissa98 Group Title

I was told to graph it.

8. geoffb Group Title

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

9. marissa98 Group Title

well. Iwas plugging in numbers for x.

10. geoffb Group Title

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

11. Stephchen Group Title

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

13. marissa98 Group Title

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

14. geoffb Group Title

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..
