That is 1075 / 56 = 19.2
Answer: 19
The statement which is true about the given graph is that f(x)<0 in the interval (-∞,3) which is option 3.
Given Graph of a function
We have to choose a statement which is correct about the function whose graph is given.
The graph of a function tells us about the domain and range of the function. The values on y axis are the codomain of the function and the values on x axis are the values of domain.
When we see the graph we can find that x=-∞ to x=3 the values are negative means when we put the values of x less than 0 we will get negative number. For example if we put the value of x=-1, we will get -20 which is a negative number.
Hence the third statement is true for the given graph which is that it has values less than zero in the interval (-∞,3).
