Find the linear approximation of the function g(x)
V1 + x at a = 0. Use it to approximate the numbers 0.95 and 1.1.
Use technology to graph g and the tangent line in the same viewing window.
Step 1
Recall that the linearization of g(x) for x = a is given by
L(x) = g(a) + g'(a)(x − a).
The first step is to find g'(x) so that it can be used to find g'(a).
√√1 + x = (1 + x) ¹/⁹, we have
1/9
1
For g(x) =
g'(x):
g'(0)
Therefore, at a = 0 we have
1/9
=
9
g(x)
9
=
(1 + x)
Step 2
Now, at a = 0, we have g(0) =
=
Therefore, at a = 0, we have
1/9
0.95 = 1 +
-8
9
1 + x g(0) + g'(0)(x −0)
=
-8/9
We will now use this linear approximation to approximate 0.95. We first need to rewrite 0.95 in the form 1 + x, where
x is a numerical value.
