For you, a job where things are predictable is better than a job where they are not predictable.

I would say a job where things aren't predictable would be better. When your job is unpredictable you never know what the next day holds for you and it creates excitement and makes you curious about what will happen next. You don't get stuck in the same old routine and get bored with your job.

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.
