Suppose total benefits and total costs are given by b(y) = 100y − 8y2 and c(y) = 10y2. what is the maximum level of net benefits
olga nikolaevna [1]
Whenever you face the problem that deals with maxima or minima you should keep in mind that minima/maxima of a function is always a point where it's derivative is equal to zero.
To solve your problem we first need to find an equation of net benefits. Net benefits are expressed as a difference between total benefits and total cost. We can denote this function with B(y).

B(y)=b-c
B(y)=100y-18y²

Now that we have a net benefits function we need find it's derivate with respect to y.

\frac{dB(y)}{dy} =100-36y

Now we must find at which point this function is equal to zero.

0=100-36y
36y=100
y=2.8

Now that we know at which point our function reaches maxima we just plug that number back into our equation for net benefits and we get our answer.

B(2.8)=100(2.8)-18(2.8)²=138.88≈139.

One thing that always helps is to have your function graphed. It will give you a good insight into how your function behaves and allow you to identify minima/maxima points.

If f(x) = 8x2 + 4x - 12. Find f(2)<br> f(2)=
posledela

Answer:

f(2) = 28

Step-by-step explanation:

\rm f(x) = 8 {x}^{2}  + 4x - 12

\rm Evaluate \:  8 x^2 + 4 x - 12 \:  where  \: x = 2: \\  \\  \rm \implies f(2) = 8 \times {2}^{2}  + 4 \times 2 - 12 \\  \\   \rm \implies f(2) = 8 \times 4 + 8 - 12 \\  \\   \rm \implies f(2) = 32 - 4 \\  \\   \rm \implies f(2) = 28
