Answer:
.
In other words, the in could be any real number as long as for all integer (including negative integers.)
Step-by-step explanation:
The tangent function has a real value for real inputs as long as the input for all integer .
Hence, the domain of the original tangent function is .
On the other hand, in the function , the input to the tangent function is replaced with .
The transformed tangent function would have a real value as long as its input ensures that for all integer .
In other words, would have a real value as long as .
Accordingly, the domain of would be .
0.4
do 6÷15
=0.4
whenever u have to turn a fraction into a decimal just divide the numerator (top number) by the denominator (bottom number)
Adding 3
-3 + 3 = 0
0 + 3 = 3
3 +3 = 6
6 + 3 = 9
15
I'm not really sure how, try telling her to ask her teacher, it's kinda hard to explain but, yeah 15.
this is the answer I check it twice
