I have a question on the rankine cycle with a closed feedwater heater. My thermo book says that in an ideal closed feedwater heater, the feedwater is heated to the exit temperature of the extracted steam. I don't really understand this. I know the bleed steam from the turbine is cooled to a...
What does the antiderivative of a distance versus time graph represent? What does the antiderivative of the anitiderivative of a distance versus time graph represent? I think the units would be meters multiplied by seconds. Thanks.
I think I figured it out.
f(5) would be a local minimum
I think I messed up because I choose f(0) as a point to the left of f(5) instead of a point in between 1 and 5.
Do you have to include your vertical asymptotes when you are trying to find out if the function is increasing or...
f'(5) is neither a minimum or a maximum
Why is this a critical number? The graph is increasing to the left of -1 and decreasing to the right of -1. The graph is not changing at 5.
I have found a critical number at x=5 but I don't know if that is correct.
I have a vertical asymptote at X=1 and a horizontal at y=-1
My derivative of the function is (x-5)/(x-1)^3 but I am not sure f this is right either.
I don't know which points to use to tell if it is increasing or...
Could someone find the domain, intercepts, asymptotes, critical numbers, local min and max, absolute min and max, concavity, and inflection points of the function: (2+x-x^2)/((x-1)^2)
Thank you it would be much appreciated
