A shop selling kimonos determines that its monthly sales, in thousands of yen, x weeks after releasing a new collection is given by the following function $f(x) = 6x^3 + 4x^2 - 4x + 2$ a) Find $f'(4) =$ b) Find $f''(5) =$ c) What is the meaning of the your answers in a) and b)?

Step 1
To find f(4), we substitute x = 4 into the function f = 6x + 4x^2 - 4x + 2: f(4) = 6(4) + 4(4)^2 - 4(4) + 2 = 24 + 4(16) - 16 + 2 = 24 + 64 - 16 + 2 = 74 + 2 = 76 b) Show more…

The monthly sales for January for a whole foods market was $\$ 60,000$ and has increased linearly by $\$ 2500$ per month. The amount in sales $f(x)$ (in \$) is given by $f(x)=60,000+2500 x$, where $x$ is the number of months since January. a. Determine if the function $g(x)=\frac{x-60,000}{2500}$ is the inverse of $f$. b. Interpret the meaning of function $g$ in the context of this problem.
