DETAILSSCALCET8 2.7.004.Consider the curve y = x. Find the slope of the tangent line to the curve at the point (1, 0).(D) Find an equation of the tangent line in part (a):(c) Graph the curve and the tangent line:

SOLVED:Find the points (c, f(c)) where the line tangent to the graph of f(x)=x^3-x is parallel to the secant line that passes through the points (-1, f(-1)) and (2, f(2)).
