In order to find any of the info we need we have to find the first derivative of the equation. If 
, then 
. We are told to find the slope at point (1, 7). Using that x value in our derivative will give us the slope of the line at that point. y' = -(1)^2+8. So y' = 7. That's the slope of the line. Now we will use that slope along with the x and y coordinate in the slope-intercept form of a line to solve for b. 7 = 7(1) + b so b = 0. Our equation then is y = 7x. If you graph these in the same window on your calculator, you can see how perfectly that align at the given point. It's really quite perfect.
Answer:
Step-by-step explanation:
In the expressions, the value at which the domain of the function will be the set of all real numbers except x=4.1 is the value at which 4.1 makes the denominator equal to zero, i.e makes the fraction undefined.
Given the options
Setting the denominator to zero, x-4.1=0, x=4.1. The fraction is undefined at x=4.1
Setting the denominator to zero, x+4.1=0, x=-4.1. The fraction is undefined at x=-4.1
Setting the denominator to zero, x-2.8=0, x=2.8. The fraction is undefined at x=2.8
Setting the denominator to zero, x-2.5=0, x=2.5. The fraction is undefined at x=2.5
Therefore, function that has a domain of all real numbers except x=4.1 is:
