The function whose graph is given by: y = sin x-3 because sin starts at 0 and goes up. Therefore, the correct option is D.
Function is a type of relation, or rule, that maps one input to specific single output.
A graph contains data of which input maps to which output.
Analysis of this leads to the relations which were used to make it.
For the example, if the graph of a function is rising upwards after a certain value of x, then the function must be having increasingly output for inputs greater than that value of x.
If we know that function crosses x axis at some point, then for some polynomial functions, we have those as roots of the polynomial.
The function whose graph is given by: y = sin x-3 because sin starts at 0 and goes up.
