I really need help with figuring out how to calculate b, I've been really confused. If f(x)=2x2−4x+6 , find f'(3) =8

Use this to find the equation of the tangent line to the parabola y=2x2−4x+6 at the point (3,12) . The equation of this tangent line can be written in the form y=mx+b where m is: 8

and where b is:

This is the number of parts out of 100, the numerator of a fraction where the denominator is 100. submit

What number line represents the solution set for the inequality -1/2 greater than or equal to 4

Apoll is being conducted at a mall nothingto obtain a sample of the population of an entire country. what is the frame for this type of​ sampling? who would be excluded from the survey and how might this affect the results of the​ survey? what is the frame for this type of​ sampling? a. the frame is people who need new clothes. b. the frame is people who shop at the mall. c. the frame is people who like to shop. d. the frame is the entire population of the country. who would be excluded from the survey and how might this affect the results of the​ survey? a. any person that does not need new clothes is excluded. this could result in sampling bias due to undercoverage. b. any person who does not shop at the mall is excluded. this could result in sampling bias due to undercoverage. c. any person who does not shop at the mall is excluded. this could result in nonresponse bias due to people not participating in the poll. d. there is nobody that is being excluded from the survey.
