Calculate the average rate of change for the function f(x)=x^4+3x^3-5x^2-2, from x=-1 to x=1

Ifound this on google “that means that the graph of a function with direct variation has these features: it is a straight line: because the slope is the ratio y/x = k. it passes through the origin (0,0): because y = kx = k (0) = 0.” i hope this you for what your looking for
