Question 6

Which describes how to graph by transforming the parent function?

Revolt · Accepted Answer

Reflect the parent function over the x-axis, and translate it 8 units to the left.

Question 7

Which statement best describes and the parent function ?

Revolt · Accepted Answer

The ranges of g(x) and f(x) are the same, and their domains are also the same.

Question 8

The graph of the parent function f(x) = x3 is translated to form the graph of g(x) = (x + 5)3 − 6. The point (0, 0) on the graph of f(x) corresponds to which point on the graph of g(x)?

Revolt · Accepted Answer

(−5, −6)
