Question

The function C(x) = x3 - 15x + 14 gives the cost tomanufacture x units of a product. What is the cost to manufacture70 units?$333,459$312,980$324,768$341,964

Answer 1

$341,964

Explanation

Step 1

to solve this replace the valur of x in the equation with 70

$C(x)=x^3-15x+14$

so, when x=70

$\begin{gathered} C(x)=x^3-15x+14 \\ C(70)=70^3-15\cdot70+14 \\ C(70)=343000-1050+14 \\ C(70)=341964 \end{gathered}$

so, the answer is

$341,964
