Question 1026733: For f(X) = X^4, the derivative is known to be -4 at X = -1. find the equation of the tangent line to the graph of y = f(X) at the point with x-coordinate -1 Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! The line has slope -4 and goes through point with x= -1, and therefore f(x)=(-1)^4=1
y-1=-4(x+1)
y-1=-4x-4;
y= -4x-3
