Question

Which equation matches the graph?

f( x) = x3 + 2
f( x) = ( x + 2) 3
f( x) = ( x - 2) 3
f( x) = x3 – 2
f( x) = x3

Answer 1

Option D

Explanation:

The parent function is y=x³

• y=x³

Translate 2 units down

• y=x³-2

This is showing on graph

Option D is correct

Answer 2

• D. f(x) = x³ - 2

Explanation:

The graph is the translation of the parent function 2 units down.

The parent function is f(x) = x³.

The translation is f(x) - 2

The function is:

• f(x) = x³ - 2

Correct choice is D
