Please help me write at least like a paragraph... Goal
Your task is promote an understanding of ethnic and racial prejudice.

Role
You have been asked to lead a seminar to promote multicultural sensitivity.

Audience
The target audience is a group of teachers.

Situation
The context you find yourself in is to imagine that you are hired to lead a seminar to promote multicultural sensitivity among the faculty of a school district. You walk in and find that all teachers have grouped themselves by ethnicity.

Product, Performance, and Purpose
You need to develop a plan to optimize the interactions among the teachers during the next few hours and to promote an understanding of ethnic and racial prejudice.

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.
