find the limit as x approaches c of the average rate of change of each function from c to x.
$c = 0; f (x) = 3 x^{3} - 2 x^{2} + 4$

Short Answer

Expert verified

The limit is $0$

Step by step solution

Step 1. Given information is

$c = 0; f (x) = 3 x^{3} - 2 x^{2} + 4$

Step 2. An average rate change of function f from point c to x

$\frac{鈭� y}{鈭� x} = \frac{f (x) - f (c)}{x - c} \frac{鈭� y}{鈭� x} = \frac{3 x^{3} - 2 x^{2} + 4 - (3 c^{3} - 2 c^{2} + 4)}{x - c} \frac{鈭� y}{鈭� x} = \frac{3 x^{3} - 2 x^{2} + 4 - (3 {(0)}^{3} - 2 {(0)}^{2} + 4)}{x - 0} \frac{鈭� y}{鈭� x} = \frac{3 x^{3} - 2 x^{2} + 4 - 4}{x} \frac{鈭� y}{鈭� x} = \frac{3 x^{3} - 2 x^{2}}{x} \frac{鈭� y}{鈭� x} = \frac{x (3 x^{2} - 2 x)}{x} \frac{鈭� y}{鈭� x} = 3 x^{2} - 2 x$

Step 3. Solving for limit we get,

$\lim_{x 鈫� c} \frac{鈭� y}{鈭� x} = \lim_{x 鈫� c} \frac{f (x) - f (c)}{x - c} \lim_{x 鈫� c} \frac{鈭� y}{鈭� x} = \lim_{x 鈫� c} (3 x^{2} - 2 x) \lim_{x 鈫� c} \frac{鈭� y}{鈭� x} = 3 {(0)}^{2} - 2 (0) \lim_{x 鈫� c} \frac{鈭� y}{鈭� x} = 0$
