The linear approximation at x=0 to f(x)= sqrt (7+6x) is y=

  for f(x)=sqrt(7+6x) Calculate the slope at x0=0, i.e. m=f'(x0)=f'(0) and the value of y0=f(x0) to give the tangent point (x0, f(x0))=(0,f(0)) The linear approximation at x=0 is given by y = m(x-x0)+y0 If you have difficulties finding the derivative of f(x), post for more information.
