Does the 3 call for me to increase my interval by 3 times making it 0≤x≤540 ?
tan ( 3x ) = -1 = tan ( pi - pi/4 ) = tan ( 3pi/4 ) that gives 3x = 3pi/4 and so x = pi/4
also tan ( 3x ) = -1 = tan ( 2pi - pi/4 ) = tan ( 7pi/4 ) this implies 3x = 7pi/4 thus x = 7pi/12
Now you can draw the correct conclusion
Hi Curt26,
No.
question specifically mentions your domain of x.
its not possible to change the domain.
the only difference that 3x does is to make you include some more values of x
pi= 180 degrees
what's the value of 7pi/12
--------------------------
dont be afraid to have multiple answers.
x can have multiple values.
Cheers
