Answer:
1) Cos
2) 1
3) π
4) 1
5) y < 0
Step-by-step explanation:
1)
Cos
2)
The y-intercept is the value of y when x=0, ie the value of y when the line meets the y-axis. We can see from the graph that this is 1.
3)
The x-intercept is the value of x when y=0, ie the value of x when the line meets the x-axis. We can see from the graph that the smallest positive value of x when the line crosses the x-axis is π.
4)
Highest y value from graph is 1, and besides, for cos graphs, y≤1.
5)
We can see from the graph that between x=π and x=2π, the function is bellow the y-axis, ie y<0.
