Which equation represents f(x)?<br>

QveST [7]

Answer:

C. $y=\sqrt[3]{-x} -1$

Step-by-step explanation:

Consider the eparent function $y=\sqrt[3]{x}$ The graph of this function is shown in the attached diagram - red curve.

Reflect this graph across the y-axis, you'll get the blue line which equation is

$y=\sqrt[3]{-x}$

Translate this graph 1 unit down, then you'll get green line (that is exactly the graph from your image) and the function for this line is

$y=\sqrt[3]{-x} -1$
