Best ResponseYou've already chosen the best response.0First of all for solving this question do you know the conception of : Derivatives. and i know you can then definitely can solve the question on your own

Best ResponseYou've already chosen the best response.2take dervitive first of all : can you do that?

Best ResponseYou've already chosen the best response.1I dont remember reading anything about derivatives in the text book

Best ResponseYou've already chosen the best response.1A little. I remember seeing it. Didnt go into much detail

Best ResponseYou've already chosen the best response.2anyhoo first we must take the derivative aka differential. x^2+5*x luckily this one is one of the most basic and using the rules aka formulas. http://myhandbook.info/form_diff.html look at constant rule, sum rule and power rule :D try it out if you can

Best ResponseYou've already chosen the best response.1what do i plug in for d?

Best ResponseYou've already chosen the best response.2and d/dx just means the derivative operator so d/dx(x^2+5*x) means derivitve of x^2+5*x with respect to x d/dx(x^2)+ d/dx(5*x) the sum rule this makes it more easy :) seperated into 2 small derivatives instead of one big one. we handle it as 2 seperate problems d/dx(x^2)= 2x by the power rule simply decrease the exponent by 1 and multiply the variable and coefficient by the exponent you just decrased. you get 2 :). d/dx(5*x) = 5 by factor rule now you plug back in because you did them seperately 2x+5 and that is derivative :) with me so far?

Best ResponseYou've already chosen the best response.22x+5 is also a tangent function which gives the slope of the tangent at any given x. For example at x=0 the slope is 5. they want it at 4 tho. So plug it in 2(4)+5=8+5=13 That is your answer :)

Best ResponseYou've already chosen the best response.2weird tho if you not familiar with calc 1 concepts then it is weird problem to do.

Best ResponseYou've already chosen the best response.0hmm maybe if we do: x1 = 3 x2 = 5 y1 = 9+15 = 24 y2 = 25+25 = 50 M = (y2y1)/(x2x1) = (5024)/(53) = 26/2=13

Best ResponseYou've already chosen the best response.0Voila, the answer given to us by calculus matches up: f'(4) = 2x+5 = 2*4+5=13
