The following statement defines a relation R in the natural numbers N. state whether or not each relation is symmetric 1. x is less than or equal to y 2. x+y =10
Never mind, I got it!
Y=5x^4 -24x^3+24x^2+17 is concave down for which interval? A) x<0 B) x>0 C) x<-2 or x>-2/5 D) x<2/5 or x>2 E) 2/5 < x < 2 I know you take the second derivative...but I keep getting stuck with something that won't factor right?
If x^2=25-y^2, what is the value of [(d^2)(y)]/(dx^2) at the point (3,4)?
Okay, well, I don't know how the tracher's getting her answers then.,.
Factor 5x^2 -6x-4 I must be having an off day or something; this can factor, right!?
Calculus PLEASE HELP
Given that C(x)=2x^3-21x^2+36x+1000 is a cost function, determine the intervals for which the cost is increasing. Determine any intervals for which the marginal cost is increasing. Marginal cost is when you derive the cost function, correct? So do you do the second derivative ...
