Which of the following describes the graph of y=\sqrt[3]{8x-64}-5 compared to the parent cube root function?
Question
Answer:
Answer:Stretched by a factor of 2 and translated 8 units right and 5 units downStep-by-step explanation:Given [tex]y =\sqrt[3]{8x-64}-5[/tex]
Taking greatest common factor.
[tex]y =\sqrt[3]{8 \times (x-8)}-5[/tex]
Separating the cube root over the multipliers
[tex]y =\sqrt[3]{8} \times \sqrt[3]{x-8}-5[/tex]
[tex]y = 2 \times \sqrt[3]{x-8}-5[/tex]
The parent cube root function is
[tex]y =\sqrt[3]{x}[/tex]
Stretched by a factor of 2 is equal to
[tex]y =2 \times \sqrt[3]{x}[/tex]
Then, translated 8 units right is equal to
[tex]y =2 \times \sqrt[3]{x - 8}[/tex]
Finally, translated 5 units down is equal to
[tex]y =2 \times \sqrt[3]{x - 8} - 5[/tex]
