The difference of course is the symbol between the f and g letters.
The circle notation means we're doing a function composition.
Writing is the same as saying where g is the inner function.
Here's an example
f(x) = x^2
g(x) = 3x
f( g(x) ) = ( g(x) )^2 ... note how x is replaced with g(x)
f( g(x) ) = ( 3x )^2
f( g(x) ) = 9x^2
-------------------
On the other hand, the dot notation means we multiply the f(x) and g(x) functions.
Going back to the previous example, we could say
There isn't really any work to show, but that is correct!
The calculator rounded the answer.
The exact value of is , i.e. a zero followed by infinitely many 6s.
The calculator can store only 4 decimal digits, so it has to approximate the number. By doing so, it has to "choose" between 0.6666 and 0.6667.
Since the next digit is a 6, the approximation is 0.6667.
In fact, if you have to approximate with four decimal digits, you have to look at the fifth. If it is between 0 and 4, you use your fourth digit. For example, 0.35742 is approximated by 0.3574.
If instead the fifth digit is between 5 and 9, you raise the fourth digit by one: 0.57836 is approximated by 0.5784
Answer:6+3w
Step-by-step explanation:
So, our number is "W"
SO, 6 more than three times w is
6+3w
Three times w=3w
Then, it says 6 more, so we add 6
