In a presidential election year, three states decide to change the date of their primary to be months earlier in the primary season than in years past.
In which of the following ways will this decision most likely affect primaries that occur later in the season?
Money will be wasted if candidates drop out of the race.
The change in date may fracture political parties and prolong the primary season.
Early voters' votes will not count if their candidates drop out of the race before the primary.
The ballots of later primary states will list names of candidates who are no longer in the race,

Pressure and heat that's what i think( don't report if wrong)

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.
