What does it mean to be human? Logically, does it mean to think like a nihilist? Like we’re merely just dust and atoms of something bigger(the universe). Why do we “REALLY” exist? Am I wrong for thinking like this

Well to be honest, we are insignificant. But that doesn’t mean we should surrender to that way of thinking. When you’re at your lowest point, your open to the greatest change

You need to figure out at which x-value does the graph has a tangent line slope of -1.remember, the derivative is the slope of the tangent line. so find the derivative function and set it to equal -1 to find the x-value that will have a tangent line slope of 0.differentiate with the chain rule.    set the derivative to equal -1 and solve for x.      take log base 10 of both sides. also recall that  .    so the x-coord of the point of tangency is .the y-coordinate of this point of tangency can be calculated using the original function:     using point-slope form, the equation of the tangent line is      the x-intercept of this tangent line is when the graph is at y=0.    this rounds off to  .choice c.
