For this case we have the following functions:
By definition we have to:
Substituting:
The range of the function is given by all values of "and" valid. That is, all the real numbers.
ANswer:

40% of 45 =
.40 × 45 = 18
this is how many comedies he has.
45-18 = 27 action adventures.
The easiest way I know is to multiply the divisor by different numbers to see how many times it will go into the dividend. multiplying 486 by 2 or three and seeing which one gets closest.

On the unit circle, the angle at which the x-value = √2/2 and the y-value = √2/2 is at 45°.
tan 45° = (√2/2)/(√2/2) = 1.
