The image of the function f: R -> R, defined as f(x) = (x-2)^4, is confirmed to be [0, ∞). Participants agree on this conclusion, emphasizing the importance of using LaTeX for clarity in mathematical expressions. The function's output is non-negative for all real numbers x, as it represents a fourth power. Overall, the discussion reinforces the correct understanding of the function's image.

What is the image of the function f: R -> R, f(x) = (x-2)^4

I think [0,∞)

Am I right?

Yes, you are right. ;) Good job! Just try to use LaTeX when typing out your math. It would look like this: $f: \mathbb{R} \to \mathbb{R}, f(x) = (x-2)^4$ and the image is $[0, + \infty)$.
 
I have been insisting to my statistics students that for probabilities, the rule is the number of significant figures is the number of digits past the leading zeros or leading nines. For example to give 4 significant figures for a probability: 0.000001234 and 0.99999991234 are the correct number of decimal places. That way the complementary probability can also be given to the same significant figures ( 0.999998766 and 0.00000008766 respectively). More generally if you have a value that...
