Answer:
The way is in the steps.
Step-by-step explanation:
y = sin(x) has a period of 2π and amplitude of 1.
a) y = a * sin b(x - c) - d
y = 7/2 * sin 2/3(x - π/4) - 2
- [tex]a=\frac{7}{2}[/tex]
- [tex]b=\frac{2}{3}[/tex]
- [tex]c = \frac{\pi }{4}[/tex]
- [tex]d=-2[/tex]
b) amplitude is affected by a = 7/2 , so the amplitude is 7/2.
The range is (-5.5 , 1.5) because looking at the graph, but also by making a table to help find the range.
c) Period = 2π/b
Period = 2π/2/3 = 3π
d) Horizontal Shift left/right is dependent on c.
c = π/4 , so Horizontal Shift to the Right by π/4
Vertical Shift up/down is dependent on d.
d = -2 , so Vertical down shift by 2.
