Question

Which of the following functions has a graph with amplitude of 5?j(x)=sinx+5h(x)=cosx5g(x)=cos5xm(x)=−5sinx

Answer 1

The sine function or cosine function can be expressed as

$x=A\sin (\omega t+\varphi),x=\cos (\omega t+\varphi)$

Where, A is amplitude.

Here our given problem, consider m(x) = -5 sinx, where A=5.

Therefore, the required answer is m(x) = -5 sinx.
