-3x-14 should be the answer
Given:
The inequality is

To find:
The value of x and then graph on the number line.
Solution:
We have,

Subtracting 19 from both sides, we get


It means all the real values of x which are less than or equal to 4 are in the solution set. So, an arrow approaches towards left from x=4 as shown in the below figure.
Answer:The amplitude:30
so a:-30
the period is:12
so b: pi/6
