Question 1189935: ILLUSTRATION OF THE GRAPH
1. The units in the x-axis must be in terms of 𝜋.
2. RF must be illustrated in the interval: [−2𝜋, 2𝜋]
3. TF must be illustrated accordingly patterned to RF to clearly see the translation.
4. Emphasize the dots of the x-intercepts with its coordinate.
5. Indicate the units on the x-axis where the graph reaches the highest point and lowest point.
Reference function:y= cos x
General Form of Sine Function: 𝑦 = 𝑐 + 𝑎 cos 𝑏(𝑥 − 𝑑)
PROPERTIES OF A CIRCULAR FUNCTION:
1. Period
2. Amplitude
3. Intercepts
4. Vertical Translation, 𝑐
5. Horizontal Translation, �

𝑇𝐹1: 𝑦 = −2 cos 𝑥
𝑇𝐹2: 𝑦 = −2 cos 4𝑥
𝑇𝐹3: 𝑦 = −2 cos(4𝑥 − 𝜋)
𝑇𝐹4: 𝑦 = −1/2-2 cos(4𝑥 − 𝜋)
