Question

ƒ(x) = x2 + 2x, x0 = 1, dx = 0.1 

In Exercises 39-44, each function f(x) changes value when x changes
from x, to xo + dx. Find
a. the change Af = f(xo + dr) – f(x);
b. the value of the estimate df = f'(x) dx; and
%3D
c. the approximation error |Af - df|.
y = f(x)/
Af = f(x, + dr) –f(x)
(Xo. f(ro))
df = f'(xo) dx
