Question

The graph of the cubic toolkit function is reflected across the x-axis. Which of the following describes the end behavior of the new function’s left end (approaching negative infinity)?

Answer 1

Given that;

The graph of the cubic toolkit function is reflected across the x-axis. i.e.

`f(x)=x^3`

Is reflected across the x-axis

`f(x)=-x^3`

The graph is shown below

From the graph above,

We can deduce that the end behavior of the graph on the left side, it is approaching up.

Hence, the answer is up
