Question

The graph of the parent function f(x) = xº is translated to form the graph of g(x) = (x – 4) 3 – 7. The point (0, 0) on the
graph of f) corresponds to which point on the graph of g(x)?

1. Answer: The point (0, 0) corresponds to the point (4, -7)

Step-by-step explanation:

We have the function f(x) = x^3

And we transform this to get:

g(x) = (x – 4)^3 – 7

Here we have a vertical translation and a horizontal shift, let’s define these two shifts:

Vertical shift.

If we have a function f(x), a vertical shift of N units is written as:

g(x) = f(x) + N

This will move the graph of f(x) up or down a distance of N units.

if N is positive, then the shift is upwards

if N is negative, then the shift is downwards.

Horizontal shift.

If we have a function f(x), a horizontal shift of N units is written as:

g(x) = f(x + N)

This will move the graph of f(x) to the right or left a distance of N units.

if N is positive, then the shift is to the left

if N is negative, then the shift is to the right.

Then if we start with f(x), g(x) is a translation of 7 units down and 4 units to the right.

This means that any point (x, y) that belongs to the graph of f(x), after the transformation will be (x + 4, y – 7)

Then the point (0, 0) of the original function corresponds to the point (0 + 4, 0 – 7) = (4, – 7) of the function g(x)

We can check this, we need to evaluate the function g(x) in x = 4

g(4) = (4 – 4)^3 – 7= 0 – 7 = -7

g(4) = -7

Then the point (4, -7) belongs to the graph of g(x).
