Given f(x) = 2x^2 - 5, what is f(3)? 10 points best answer & I'll answer yours :)

So what do I do? Do I just divide both sides by 3 or something? 10 points best answer :D if you want me to answer yours, just ask and I will!-f(x) is a notation in mathematics that states f as a funct

Calculus:Differentiate problem please helpppppp

Find derivitative of f(x)=3x^5 ln(x) AND find f (e^4) I found the f (x)= 3(x^4+(5x^4)log(x))... this is correct, but i dont get f (e^4) Can someone please help me with f (e^4) of f(x)=3x^5 ln(x) Th

How would this algebra equation be solved

I simplified the original problem to:21u - 35 = -18u + 90 Can someone walk me through this equation? thanks.-21u - 35 = -18u + 90 21u - 35 + 18u = 90 add 18u to each side 21u + 18u = 90 + 35 add 35 t

Can someone factor x^2-x-a-a^2 for me

Step-by-step please :)-x^2-x-a-a^2 = x^2-a^2 - x-a = (x+a)(x-a) - (x+a) = (x+a)(x-a-1)-Well, just try to look at it as the familiar situation ax^2 + bx + c; only that c is more complicated than usual

Can anybody solve this Quadratic problem by factoring ( without using Quadratic formula) (x-3)(x-4)=34/(33^2)

Start solving by completing square: (x-3)(x-4)=34/(33^2) x^2 - 7x + 12 = 34/1089 x^2 - 7x =34/1089 -12 x^2 - 7x + 49/4 =49/4 - 13034/1089 (x - 7/2)^2 = 1225/4356 => go to #2 below for solution by fa
