I hope this helps you
f (x)= 3 (x-2)/(x-2)
f (x)= 3
f(6)= 3
f (8)= 3
Q) Without a calculator, we must estimate the value of the following expression:
![3-\sqrt[]{38}.](https://tex.z-dn.net/?f=3-%5Csqrt%5B%5D%7B38%7D.)
A) I estimate 3 - √38 to be approximately -3.2.
First, we estimate the value of √38. √38 is between √36 and √49, but close to √36 (since 38 is closer to 4 than it is to 9). Since √36 is 6, √38 is probably something like 6.1 or 6.2. Filling 6.2 in the expression and simplifying, we have this:

So, I expect the number 3 - √38 to be close to -3.2.
Using a calculator we find that: 3 - √38 ≅ -3.16, which it is approximately the result that we found.
Answer
Without a calculator we find that 3 - √38 ≅ -3.2.
Step-by-step explanation:
Let the number be x
2 more than a number = x + 2
I think you’d do (5,8) - (1,3) to get (4,5)
For y= -2x + 8 i think y is -2x + 8 and x is 4 - y/2
