Exercise 12 Page 343

To determine the cubic function that is obtained from the parent function, consider the transformations one at a time.

y=- 53(x-3)^3-4

Practice makes perfect

To determine the cubic function that is obtained from the parent function y=x^3 after the given sequence of transformations, let's consider the transformations one at a time.

Vertical Stretch by a Factor of 53

We will start by performing a vertical stretch on the parent function by a factor of 53. This is done by multiplying the parent function by 53. The resulting function is y= 53x^3.

Reflection Across the x-axis

Next, let's reflect the function across the x-axis by multiplying the whole function by - 1. y=(- 1)(5/3x^3) ⇔ y=- 5/3x^3 Let's draw the graph of this function.

Vertical Translation 4 Units Down

To perform a vertical translation 4 units down, we need to subtract 4 from the whole function. The result is y=- 53x^3-4.

Horizontal Translation 3 Unit Right

Finally, to perform a horizontal translation 3 units right, we need to subtract 3 from the x-variable, resulting in y=- 53(x-3)^3-4.

The cubic function that is obtained after the sequence of transformations is y=- 53(x-3)^3-4.
