Answer:

Given

f(x) = 4/(x - 2)

Find

[f(x + h) - f(x)] / h

Solution

[4/(x + h - 2) - 4/(x - 2)]/h =
4/h[(x - 2) - (x + h - 2)]/[(x + h - 2)(x - 2)] =
- 4/h*h/[(x + h - 2)(x - 2)] =
4/[(x + h - 2)(2 - x)]

Answer:

$\dfrac{ah}{a+h}$

Step-by-step explanation:

Consider similar triangles BMC and KMN.

In these triangles,

$\dfrac{BC}{KN}=\dfrac{MO}{MP},$

where O is the point of intersection of BC and MP.

Note that segment OP has the length the same as the side of the square ABCD. Hence,

$\dfrac{BC}{a}=\dfrac{h-BC}{h},\\ \\BC\cdot h=a(h-BC),\\ \\BCh=ah-aBC,\\ \\BC(h+a)=ah,\\ \\BC=\dfrac{ah}{a+h}.$
