Question

question 10 of 30
what is the amplitude in the graph of ( y = 4sin(3x - 1)+5 )?
a. 5
b. 1
c. 3
d. 4

Explanation:

Step1: Recall sine function form

The general form is $y = A\sin(Bx - C) + D$, where $|A|$ is amplitude.

Step2: Identify A in given function

Given $y = 4\sin(3x - 1) + 5$, $A = 4$. Amplitude is $|4| = 4$.

Answer:

D. 4
