Question

what is amplitude of the graph? 1 3 4 -3

Explanation:

Step1: Recall Amplitude Definition

Amplitude of a periodic graph (like a wave) is the maximum distance from the midline (equilibrium position) to the peak (or trough). It's a non - negative value, representing the height of the wave from the center.

Step2: Analyze the Graph (from Visual Cues)

Looking at the graph (even with the partial view), we can infer that the vertical distance from the midline (x - axis, since it's crossing the x - axis) to the peak (or trough) is 3. Also, amplitude cannot be negative, so we can eliminate - 3. The values 1 and 4 don't match the visual representation of the wave's height.

Answer:

B. 3 (assuming the blue option is labeled as B, following the order of options: orange - 1, blue - 3, green - 4, red - 3. The correct amplitude is 3 as it's the non - negative maximum distance from the midline to the peak/trough of the wave - like graph.)
