Question

Given the parent function f(x)=x^3 give the best description of the graph of y=x^3+3 .

a.
translated up 3 units
c.
translated left 3 units
b.
translated down 3 units
d.
translated right 3 units

Answer 1

The correct answer is A. +3, unless inside parentheses, indicates a positive vertical change, thus the function would move upward. If the function looked like 2(x^3 + 3) the change from the +3 would be horizontal (left) instead.
