Imagine that you wake up and are eating breakfast. You suddenly realize that you have a test today, and you forgot to study for it. You begin to feel nervous and afraid, and you call a friend to ask if they have studied for the same test. You learn that the test is not today, but next week, and you begin to feel much calmer, and much happier.
i. For this scenario, describe the role of your central nervous system, and each portion of your peripheral nervous system, including the somatic and autonomic portions.

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.

Of course it’s correct because you know why if you readi you did not put. any numbers but i understand so your promblem is yes and correct
