Question

Draw the graph of y= sint/2
​

Answer 1

Answer:

This function means that for every number (

x

) you insert, you will be getting its sine (

sin

) minus 2 (

−

2

).

Since each sine cannot be less than

−

1

and more than

1

(

−

1

≤

sin

≤

1

) and

2

is always subtracted, you will be always getting a certain range of numbers (Range

=

[

−

3

,

−

2

]

).

Hence, the shape of the function is such than only take certain numbers.

The function will always be under the

x

'

x

axis, because highest possible value of

sin

x

is

1

and

2

is always subtracted, so the function will always be equal to a negative value.

graph{y = sinx - 2 [-10, 10, -5, 5]}

I hope this makes sense to you.
