How do I write a sine function with no horizontal shift for the sinusoid shown

Graph the system of inequalities presented here on your own paper, then use your graph to answer the following questions: y < 4x − 8 y is greater than or equal to negative 5 over 2 times x plus 5 part a: describe the graph of the system, including shading and the types of lines graphed. provide a description of the solution area. (6 points) part b: is the point (5, −8) included in the solution area for the system? justify your answer mathematically. (4 points)

What value is a discontinuity of x squared plus 8 x plus 4, all over x squared minus x minus 6?

Iknow its nothing to do with education, but what type of thing should i wrote here? ? : ) its for mcdonald's btw.
