Given information
Step-by-step explanation
Step 1.
Using a calculator, I found that
And that
We know that
Where
As increases the slope of the function at increases.
By definition, is a number such that the slope of is 1 at
We saw earlier that slope of for is less than 1 and for is more than 1 .
Therefore, the slope of must be between and , because the slope of when is 1 .
