What is a reasonable percent error in chemistry?

1 answer:

8 0

For physics, we use half the smallest division of the equipment used.
For chemistry, it should be the same.

The formula for percent error: delta(x)/x * 100% = delta(y)/y

Hope I helped :)

Write the inverse function for the function, ƒ(x) = 1/2x + 4. Then, find the value of ƒ -1(4). Type your answers in the box. ƒ -

katrin2010 [14]

As you know, to get the inverse of any expression, we start off by switching the variables about and then solving for "y",

$\bf \stackrel{f(x)}{y}=\cfrac{1}{2}x+4\qquad \qquad \stackrel{inverse}{\underline{x}=\cfrac{1}{2}\underline{y}+4}\implies x-4=\cfrac{1}{2}y
\\\\\\
2x-8=\stackrel{f^{-1}(x)}{y}
\\\\\\
f^{-1}(4)=2(4)-8\implies f^{-1}(4)=0$
