Question
The work below is not correct. There are a few errors. Indicate
all the errors that are presented below.
f(x) = V1– a?
f(x + h) – f(x)
= lim
h→0
f' (x)
(1)
h
- (x + h)² – V1
- 72
= lim
h→0
(2)
h
1 – x² + 2xh + h² – /1 – x²
V
lim
h→0
(V1 – x² + 2xh + h² + /1 – æ²
(3)
1- x2 + 2xh + h² + 1+ x2
= lim
h→0
(4)
h
2+ 2xh + h²
= lim
h→0
(5)
= lim 2 + 2x + h
h→0
(6)
= 2 + 2x
(7)
In line (1), the Definition of the Derivative is not correct.
In line (2), f(x +h) is not evaluated correctly.
In line (3), there are 1 or more sign errors.
In line (3), the expression should be divided by the conjugate of the
numerator.
In line (4), there are 1 or more sign errors.
In line (5), there should be an x² term.
In line (5), it is not a valid step to cancel out a factor of h in the
numerator
There is incorrect use of limit notation in this work.
