Question

slope of the secant line thru the pts. (4,f(4)) & (9,f(9))
on the graqph of y=f(x)
f(x)x^2-7x

Answer 1

The slope of the secant line is just the average rate of change. You already know how to do it.

Answer 2

oh its the same? okay thanks. ;) again

Answer 3

what about the instantaneous rate of change of y=f(x)

Answer 4

with respect to x at x=4

Answer 5

It's not any different.
