Eva8 [605]
The 20th expression would be 80. Counted on my fingers xD hit 80 when i did 20 fingers. which means that if you put 20 as n, it should come out to 80, but it comes out to 84 by the answer you chose, so I'm wondering if the answer you chose was right, or if it was A

Rewrite y =<img src="https://tex.z-dn.net/?f=%5Csqrt9%7Bx%7D%20%2B45" id="TexFormula1" title="\sqrt9{x} +45" alt="\sqrt9{x} +45"
tigry1 [53]

Answer:

(1) We have been given a function: y=\sqrt{9x}+45-2

We can rewrite it using translation is:  

It is the graph of y=\sqrt{9x} translated 45 units left and 2 units down.

(2) Now, y=\sqrt{x}-5-2

So this is the graph of y=\sqrt{x} translated 5 units right and 2 units down.

(3) y=\sqrt{x}+5-2

So, this is the graph of y=\sqrt{x} translated 5 units left and 2 units down.

(4) y=\sqrt[3]{x}+5-2

It is the graph of y=\sqrt[3]{x}

translated 5 units left and 2 units down.

(5) y=\sqrt[3]{x}+5-2

It is the graph of y=\sqrt[3]{x}

translated 5 units left and 2 units down.
