In the graph,

Amplitude = 1.5 units

Period = 180°

The x-intercepts are 40°, 140°, 220°, and 320°

<h3>Determining x-intercepts </h3>

From the question, we are to determine the amplitude, period and the x-intercepts of the given graph

Amplitude is the distance from rest to crest.

In the graph,

Amplitude = 1.5 units

Period is how long from crest to crest OR trough to trough

In the graph,

Period = 180°

x-intercepts refers to the points where the graph cuts the x-axis

In the graph,

The x-intercepts are 40°, 140°, 220°, and 320°

Answer/Step-by-step explanation:

Scale factor: 1/4

<em>AC = DF  and 10 ÷ 2.5 = 4</em>

<em>10 x 1/4 = 2.5</em>

<em />

DE length: 5

<em>AB = DE </em>

<em>20 x 1/4 = 5</em>

<em />

BC length: 30

<em>EF = BC</em>

<em>(Because EF is the dilation) 7.5 x 4 = 30</em>
