Question

If the local minimum of y≈ -15.4 and it occurs at x≈___ then what is the local minimum of x?

Answer 1

Solution:

Given the function;

$\begin{gathered} f(x)=-0.3x^3-0.5x^2+5x-4 \\ \\ -6The graph of the function is;

Thus, option A is correct.

The local maximum is;

[tex]y\approx1.64\text{ and it occurs at }x\approx1.87$

The local minimum is;

$y\approx-15.4\text{ and it occurs at }x\approx-2.98$
