Question

question 6 of 10
what is the amplitude of the graph of ( y = 4sin(2x - 1)+3 )?
○ a. 3
○ b. 2
○ c. 4
○ d. 1

Explanation:

Step1: Recall sine function form

The standard form of a sine function is $y = A\sin(Bx - C) + D$, where $|A|$ is the amplitude.

Step2: Identify A in the given function

Given $y = 4\sin(2x - 1) + 3$, $A = 4$. Amplitude is $|4| = 4$.

Answer:

C. 4
