Q. What is the amplitude of

h(x)=-5 \cos (2 \pi x+5)-2 ?

\newline

units

Identify standard form: Identify the standard form of a cosine function and the amplitude. $\newline$ The standard form of a cosine function is $A\cos(Bx + C) + D$ , where $A$ is the amplitude, $B$ affects the period, $C$ is the phase shift, and $D$ is the vertical shift.
Compare with given function: Compare the given function $h(x)=-5\cos(2\pi x+5)-2$ with the standard form. $\newline$ In the given function, $A = -5$ , $B = 2\pi$ , $C = 5$ , and $D = -2$ . The amplitude is the absolute value of $A$ .
Calculate amplitude: Calculate the amplitude. $\newline$ The amplitude is $|A| ext{, which is }|-5|$ . Therefore, the amplitude is $5$ .
