You need to learn how to do derivatives.
Find the equation of the straight line that is tangent to the graph of f(x)=(x+1)^0.5 and parallel to x-6y+4=0
my attempt:
y=x^0.5+1^0.5
y'=0.5x^-0.5
M_t=0.5/sqrt(x)
not sure if I am doing it right and where to head from here..
please state the steps needed to finish this question. Thank you
