Ответ:
f'(12)= 5
Step-by-step explanation:
Use the data in the table to approximate f ′(12).
x3471113
f(x)28101222
f'(12) is nothing but the slope at x=12
To find slope at x=12 we two points from the table x=11 and x=13
(11,12) and (13,22)
Slope formula =![\frac{y2-y1}{x2-x1}](/tpl/images/0388/4395/71a0a.png)
(11,12) is (x1,y1) and (13,22) is (x2,y2)
f'(12) =![\frac{22-12}{13-11}=\frac{10}{2}= 5](/tpl/images/0388/4395/b9286.png)
so f'(12)= 5
Ответ:
First do 3/2⁻⁷, which equals to (2/3)⁷ , which equals to 128/2187.
Then do (2x⁻¹)⁻⁵, which is x⁵/2⁵ = x⁵/32.
Multiply the two and the answer is:
128/2187*x⁵/32
= 4/2187 * x⁵
Hope this helped. : )
