Video example example 1 find the linearization of the function f(x) = x + 1 at a = 3 and use it to approximate the numbers 3.98 and 4.05 . are these approximations overestimates or underestimates? solution the derivative of f(x) = (x + 1)1/2 is f '(x) = correct: your answer is correct. and so we have f(3) = 2 correct: your answer is correct. and f '(3) = 1/4 correct: your answer is correct. putting these values into this equation, we see that the linearization is

  the linearization is y = 1/4x +5/4

  the linearization will produce overestimates

  the values computed from this linearization are ...

     f(3.98) ≈ 2.245

     f(4.05) ≈ 2.2625

Step-by-step explanation:

Apparently, you have ...

from which you have correctly determined that ...

so that f(3) = 2 and f'(3) = 1/4. Putting these values into the point-slope form of the equation of a line, we get the linearization ...

  g(x) = (1/4)(x -3) +2

  g(x) = (1/4)x +5/4

__

The values from this linearization will be overestimates, as the curve f(x) is concave downward everywhere. The tangent (linearization) is necessarily above the curve everywhere.

At the given values, we find ...

  g(3.98) = 2.245

  g(4.05) = 2.2625

yuo ned the activity or vertical angle of the form of 1,7 but 2,2 has a c4,2 as it verticie so i not have a car
