A roast turkey is taken from an oven when its temperature has reached 185°F and is placed on a table in a room where the temperature is 75°F. The graph shows how the temperature of the turkey decreases and eventually approaches room temperature. By measuring the slope of the tangent, estimate the rate of change of the temperature after an hour.

Question

jdoe0001 · Answer

got graph?    keep in mind that that is a "rate of change" thus you're really just asked what is the slope of the tangent at x = 1(hour)

or in other words,  what is the value of the derivative of the function at x = 1

anonymous · Answer

yes, but i dont know how to find the instantaneous slope at that point
