In your question, you're given this equation, and we're asked a few characteristics.
00:05
The first is amplitude.
00:06
The amplitude number is the absolute value of whatever number is multiplied to your trig function.
00:13
So in this case, that's a four.
00:15
So our absolute value of that is four.
00:18
If there is ever a negative there, the amplitude is still four.
00:22
Amplitude has to be positive.
00:24
Moving on to the period.
00:26
The period is determined by a formula, 2 .5.
00:31
Divided by b is what i typically see in textbooks and this location right here that's multiplying the x term is going to be the b value so for us your period is 2 pi divided by b the next part is we have a horizontal shift and horizontal shifts are found inside this set of parentheses adding or subtracting to the x a minus moves us to the right a plus moves this to the left...
