Consider the function f(x) = 3x^2 - 4x - 1
a) Estimate the slope of the tangent line at x =1
b) Find the y-corrdinate of the point of tangency
c) Use the coordinates of the points of tangency and the slope to find the equation of the tangent line at x = 1
I'm confused about the slopes and the EQUATION of the line...
Would the instantaneous rate of change at x = 1 be the slope for a)?
If it is, then I can use IROC = [ f(x+h) - f(x) ] /h
