Question

Rewrite to make it easy to graph using a translation.
Describe the graph

Answer 1

\[\sqrt[3]{27x-81}-5\]

Answer 2

so far i've got (27x-81)^3 -5

Answer 3

is ti powered or sqrt?

Answer 4

is what? its (27x-81) to the power of 3

Answer 5

(3^9)*[(x-3)^3] - 5

Answer 6

hmmm can you get common factor of 27x and 81 ?

Answer 7

Aim for the form of:
\[b \times \sqrt[3]{x-a} - c\]
Here is my attempt:
\[\sqrt[3]{27x-81}-5\]
\[\sqrt[3]{27(x-3)}-5\]
\[\sqrt[3]{3^3(x-3)}-5\]
\[3\sqrt[3]{(x-3)}-5\]
(Okay I have no clue if I did that right, it has been a long time since I did something like this).
3 = Slope.
-3 = Horizontal shift (To the right).
-5 = Vertical shift (Down five units).

Well I tried :3.

Answer 8

@LanguageEnthusiast where'd you get the 3 from instead of 81??

Answer 9

\[27\times3=81\]
Like jdoe said, factor :-).
