marissa98 2 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?

• This Question is Open
1. marissa98

So.

2. marissa98

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

3. marissa98

such as -1 - 1 and 2

4. marissa98

-1, 0, 1, 2 *

5. Stephchen

have you been told what the value of x is?

6. marissa98

No.

7. marissa98

I was told to graph it.

8. geoffb

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

9. marissa98

well. Iwas plugging in numbers for x.

10. geoffb

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

11. Stephchen

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

13. marissa98

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

14. geoffb

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..
