Ответ:
(g-f) (-1)= sqrt(15)
(f/g)(-1)= 0
(g+f)(2)=sqrt(3)-3
(g*f)(2)=-3*sqrt(3)
Step-by-step explanation:
We have to eval the expressions given in the point indicated.
Lets start by the first equation
(g-f)(-1)= g(-1) - f(-1)=
= ![\sqrt{15}](/tpl/images/0173/2444/11f23.png)
Now, lest continue with the others
(f/g)(-1)= f(-1)/g(-1)= (1-1)/sqrt(15)=0
(g+f)(2)=g(2)+f(2)=sqrt(3)-3
(g*f)(2)=g(2)*f(2)=sqrt(3)*(-3)=-3sqrt(3)
Ответ:
(g-f) (-1)=![\sqrt{15}](/tpl/images/0173/2444/11f23.png)
(f/g)(-1)= 0
(g+f)(2) =![\sqrt{3}-3](/tpl/images/0173/2444/6c793.png)
(g*f)(2) =![-3 \sqrt{3}](/tpl/images/0173/2444/e4458.png)
Step-by-step explanation:
Given :
To find :![(g-f)(-1)](/tpl/images/0173/2444/88602.png)
Solution :
To find :![\left ( \frac{f}{g} \right )(-1)](/tpl/images/0173/2444/fd6da.png)
Solution :
To find :![(g+f)(2)](/tpl/images/0173/2444/a9fde.png)
Solution:
To find:![(g\times f)(2)](/tpl/images/0173/2444/6dc3d.png)
Solution:
