FREE MEDAL

f(3) when f(x) = 2x + 2

f-1(4) when f(x) = 3x minus 4, all over 5

Answer 1

The first one would be 8, since you replace all of the x values with 3, and multiply where multiplying is needed. The second one is -2.4, I think. You're doing the same thing with the first one, except with -4.

Answer 2

Here's the entire problem because one of them has to have the same result as another.

Answer 3

Which of the following statements have the same result? Explain each step in solving each one.

I.f(3) when f(x) = 2x + 2
II.f-1(4) when f(x) = 3x minus 4, all over 5
III. y + 10 = 2y + 1

Answer 4

Would the answer just include one of them, or would it be like I and III have the same result, or what?

Answer 5

Yes, two of them have to have the same result.

Answer 6

But when I did III. I got y = 9

Answer 7

Yeah, y = 9. Just a second...

Answer 8

Ok, I'm a little confused. Haha

Answer 9

Wait, I don't think it has to be the same response. I think you have to put it IF there is a same answer on two of them. So I think we're done here

Answer 10

Ah. In that case, it's I.

Answer 11

Oh wait, you didn't mean what I think you meant. Nevermind.

Answer 12

Lol, well thank you! Would you mind helping me with one more?

Answer 13

Megan and Julie are stuck simplifying radical expressions. Megan has to simplify the quantity of x to the one third power, over x to the one twelfth power. Julie has to simplify the thirty second root of the quantity of x times x to the second times x to the fifth. Using full sentences describe how to fully simplify Megan and Julie’s expressions. Describe if Megan and Julie started with equivalent expressions or if they started with expressions that are not equal.
