amplitude of y=2cos(2pi(x+(2pi)/3))-5

amplitude

y = 2 cos (2 π (x + \frac{2 π}{3})) - 5

2

Solution steps

f (x) = 2 cos (2 π (x + \frac{2 π}{3})) - 5, A = 2

Therefore, the amplitude |A| is

2

2

5 x + 2 y = 4

f (x) = 6 x

f (x) = (x + 3)^{\frac{6}{7}}

f (x) = 5 - 5 x

f (x) = \frac{x - 6}{- 3 x}
