`y=f(x)=2x+1`

Draw the graph of y=f(x)=(x+1)/(x^(2)+1)

If y=f(x)=(x+1)/(2x+3), where x ne -(3)/(2) , show that: f(y)=(3x+4)/(8x+11) .

If y = f(x) = (x+2)/(x-1) , x ne1 , then show that x = f(y) .

If y=f(x)=(x+2)/(x-1),x,y!=1 then x is equal to

Draw the graph of y=f(x)=(x^(2))/(x^(2)+1) .

If y=f(x)=((x+2))/((x-1)), then (a)x =f(y)(b)f(1)=3(c)y increases with x for x<1(d)f is a rational function of x

Find the approximate value of f(3.01) when y = f(x) = x^(2)+3x+1 .

Draw the graph of: y=f(x)=3 sin (2x-1).
