Differenciate by first principles f(x) = 4x²-4x-3
zysi [14]
f(x) = 4x^2-4x-3\\
f'(x)=\lim_{h\to0}\frac{f(x+h)-f(x)}{h}\\
f'(x)=\lim_{h\to0}\frac{4(x+h)^2-4(x+h)-3-(4x^2-4x-3)}{h}\\
f'(x)=\lim_{h\to0}\frac{4(x^2+2hx+h^2)-4x-4h-3-4x^2+4x+3}{h}\\
f'(x)=\lim_{h\to0}\frac{4x^2+8hx+4h^2-4h-4x^2}{h}\\
f'(x)=\lim_{h\to0}\frac{8hx+4h^2-4h}{h}\\
f'(x)=\lim_{h\to0}{8x+4h-4}\\
f'(x)=8x+4\cdot0-4\\
f'(x)=8x-4\\

Reika [66]

The rental company to hat Oscar should use is the second company because it's cheaper.

<h3>How to illustrate the information?</h3>

The total amount charged for the first boat will be:

where h = number of hours

= 100 + 35(8)

= 100 + 260

= $360

The amount charged for the second company will be:

= 50 × 8

= 400

Therefore, the rental company to hat Oscar should use is the second company because it's cheaper.
