Best ResponseYou've already chosen the best response.1f(3) = 3^2  3(3) + 5 = 5 f(1) = (1)^2 3(1) + 5 = 10

Best ResponseYou've already chosen the best response.1derivatives are instantaneous rates of change; average rates are just last  first divided by well, ba

Best ResponseYou've already chosen the best response.1i wonder if derivs work out as well 2x3; 23 = 1 , 63 = 3 13  = 1 hmmm, might be on to something there 3+1

Best ResponseYou've already chosen the best response.2you are just looking for the slope of the secant line that lies on the curve y=x^23x+5 touching the two points (1,f(1)) and (3,f(3))

Best ResponseYou've already chosen the best response.1the instant rate of change is the slope of the tangent line to the curve at a point; also known as the derivative
