Answer:
Yes.
Step-by-step explanation:
Rational numbers can be represented as fractions with integers. The denominator must not equal 0.
is already in this form. This means that it's a rational number.
Hope this helps.
Not understanding this.
-5/2 × (3x + 4) < 6x - 3x
-15/2x - 10 < 3x
-15x - 20 < 6x
-15x - 6x < 20
-21x < 20

.
In other words, the in could be any real number as long as for all integer (including negative integers.)
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 .
