Estimate the instantaneous rate of change for x=2 for

y=x
y=x^2
y=7

  • math - ,

    If you mean the rate of change with respect to a change in x, that is the called the derivative.

    For y = x, the derivative is 1
    For y = x^2, the derivative is 2x (which is 4 when x = 2)
    For y = 7, the derivative is 0. Y does not change and is independent of x.

    If you mean the rate of the change in y with time, you would have to know the rate x changes in time.
