Question

SOMEONE PLEASE HELP ME!!!

What are the x-intercepts of the graph of the function y=6tan(x/2)-3?

Answer 1

Explanation:

`y = 6 \tan( (x)/(2) ) - 3`

Set y=0

`0 = 6 \tan( (x)/(2) ) - 3`

`3 = 6 \tan( (x)/(2) )`

`(1)/(2) = \tan( (x)/(2) )`

`\tan {}^( - 1) ( (1)/(2) ) + \pi = (x)/(2)`

Multiply both sides by 2

`2 \tan {}^( - 1) ( (1)/(2) ) + 2\pi = x`

So the x intercepts of the function is

`2 \tan {}^( - 1) ( (1)/(2) ) + 2\pi`n
