You want a linearization that will replace the function over an interval that includes the point x0. To make your subsequent work as simple as possible, you want to center the linearization not at x0 but at a nearby integer x = a at which the function and its derivative are easy to evaluate. What linearization do you use?f(x) = 
, x0 = 35.9
A. 
+ 
x
B. 3 + 
x
C. 3 - 
x
D. 3 + 
x

Provide an appropriate response.If f(x) ? 0 on the interval [a, b], then 
representsi) the area to the right of the y-axis between y = a and y = b.ii)the area above the x-axis between x = a and x = b.iii) the area below the x-axis between x = a and x = b.
A. None of the above is correct. B. Only i is correct. C. Only ii is correct. D. Either ii or iii could be correct.
