not necessarily, but how many other ways can you represent it? y=1/(x+1)
dy/dx= -1/(x+1)^2
Then formula y-y_0=m(x-x_o)
Can anyone determine what this question is asking? I am doing challenge problems and literally cannot even determine what it is asking. Okay. y=1/(x+1) Let x_0=/= -1 Find equation of tangent line at x=x_0
Simple d/dx= -1/(x+1)^2
Equation y= -(1/x_0+1)^2)x+y_0
next part: what point on the curve does the tangent line have the same slope as x=x_0 ????
Find the equation of the secant at x=x_1 and x=x_2
I have simply y-y_0=(change in y/x_2-x_2)(x-x_1)
and then the last part is way over my head in the fact that i dont even know what it is asking
What equation must x_0,x_1,x_2 obey so that the tangent line and secant lines are parallel
