Question

give example of eq, one real variable x such that it is not linear and it has 
(a)no solution
(b)unique solution
(C)two solution only
(d) infinite solution

anonymous · Answer

(a)no solution

$e^x=-1$    .....   $1+x^2=0$  ......... $\sqrt{x}+\sqrt{x+16}=3$  

(b)unique solution

$x^2=0$  .............  $\sqrt{x}=5$

(c)two solution only

$(x-1)(x-2)=0$  ..........  

(d) infinite solution

$\sin x=0$

please give grahical approch to this problem

sure

anonymous · Answer

for example $e^x=-1$   |dw:1344016174468:dw|    as u can see always $e^x >0$  so its impossible to find a  $x$ for which $e^x=-1$
