Fx) = -3x² + 2x - 7, then f(-1) =

Fantom [35]

Given:

The function is

$f(x)=-3x^2+2x-7$

To find:

The value of f(-1).

Solution:

We have,

$f(x)=-3x^2+2x-7$

Putting x=-1, we get

$f(-1)=-3(-1)^2+2(-1)-7$

$f(-1)=-3(1)-2-7$

$f(-1)=-3-9$

$f(-1)=-12$

Therefore, the value of f(-1) is -12.

Suppose that the dollar cost of producing x appliances is c(x)=1000+ 90x- 0.2x 2

Aleksandr [31]

Answer:

Step-by-step explanation:

Given that the dollar cost of producing x appliances is

$c(x)=1000+ 90x- 0.2x^2$

A) Average cost can be obtained by dividing c(x) by units = x

i.e. average cost = $\frac{1000}{x} +90-0.2x$

B) Marginal cost = dC/dx = $90-0.4x$

When x=140 marginal cost $= 90-0.4(140)\\=34$

C) We calculate

c(140) = $=1000+90(140)-0.2(140^2)\\\\=9680$

c(141) = $=1000+90(141)-0.2(141^2)\\\\\\=9713.80$

Marginal cost = difference = 33.80

Same as 34 shown in marginal cost.
