amplitude of sinusoidal functions from equation\nwhat is the amplitude of g(x)=cos((2π/3)x)+1?

Explanation:

Step1: Recall amplitude formula

For a sinusoidal function of the form $y = A\cos(Bx - C)+D$, the amplitude is given by $|A|$.

Step2: Identify A in given function

In the function $g(x)=\cos(\frac{2\pi}{3}x)+1$, we can rewrite it as $g(x) = 1\times\cos(\frac{2\pi}{3}x)+1$. Here, $A = 1$.

Answer:

$1$
