Best ResponseYou've already chosen the best response.3are we finding f'(3) either way to get the inverse, let's replace f(x) with y \[y = \sqrt[3]{x2}\] switch x and y \[x = \sqrt[3]{y2}\] cube both sides \[x^3 = {y2}\] \[x^3+2=y\]

Best ResponseYou've already chosen the best response.0\[x^{3}+2=y^{3}\] is that right?.. i have no idea I'm so stressed

Best ResponseYou've already chosen the best response.3How'd you get y^3? Remember that square roots and squares are inverse operations, right? \[(\sqrt{x})^2 = x\] \[(\sqrt[3]{x})^3 = x\]

Best ResponseYou've already chosen the best response.0oh i got confused i thought you said for ME to cube both sides lol. I'm sorry I'm extremely tired and have to get a bunch of work done by like tomorrow. ughhh. my bad

Best ResponseYou've already chosen the best response.3lol no worries, just always go over your work a bazillion times so that you can prove to yourself that your answer is right. ANYHOW, the inverse is now f(x) =x^2+2 f(3) = 3^2+2 = ??

Best ResponseYou've already chosen the best response.0wait so the answer is f(x) =x^2+2 ?

bibby

Best ResponseYou've already chosen the best response.3whoops./ you generally say inverse with a little dash f'(x) so the equation for the inverse is f'(x) = x^2 + 2 then you plug in 3 into the inverse equation (assuming that's the question)

Best ResponseYou've already chosen the best response.3uh you'd multiply by the conjugate. pardon my handwriting

Best ResponseYou've already chosen the best response.3to simplify radicals you multiply by the conjugate pair which means flipping the sign

Best ResponseYou've already chosen the best response.1You don't have to use what I gave you as a formula. Just distribute. Take each of the terms in the first grouping and multiply to each term in the second grouping

Best ResponseYou've already chosen the best response.1\[\frac{\sqrt{3}\sqrt{6}}{\sqrt{3}+\sqrt{6}} \cdot \frac{\sqrt{3}\sqrt{6}}{\sqrt{3}\sqrt{6}}\] This was the operation you were asked to perform. I was having you look at the numerator first. So looking at the numerator if we multiply the top out we would get: \[\frac{\sqrt{3} \sqrt{3}\sqrt{3} \sqrt{6}\sqrt{6} \sqrt{3}+\sqrt{6} \sqrt{6}}{(\sqrt{3}+\sqrt{6})(\sqrt{3}\sqrt{6})}\]

Best ResponseYou've already chosen the best response.1If a, b>=0 then \[\sqrt{a} \cdot \sqrt{b} =\sqrt{a \cdot b} \]

Best ResponseYou've already chosen the best response.1so basically \[\sqrt{3} \cdot \sqrt{3} =3 \text{ and } \sqrt{3} \cdot \sqrt{6}=\sqrt{18}=\sqrt{9 \cdot 2} =\sqrt{9} \cdot \sqrt{2}=3\sqrt{2}\]
