At first we have to check all the options.....
- For \(y = 2e^x\), this is not possibe because \(y = 2e^x\) expression represent only positive side's of x axis
- For \(y = 2e^-x\),This expression also represents one side of x-axis
- For \(y = e^x + e^-x\).This expression represents both sides of the x-axise.as we put \(x=0\) then \(y=2\) i.e the curve not starts from the origin
- \(y = e^x – e^-x + 2\), this expression also represents both sides of the x-axis
Can you now finish the problem ..........
Therefore ,the correct ans is (c)
