Students were enquired to answer a question at schools and to indicate what is most important for them to succeed. The one which response stood out from the rest was practice. Successful persons are not born successful; they become successful via hard work and determination. This is how you can achieve your goals. in the following paragraphs are one of the answer and question example that you may possibly implement to practice and expand your knowledge and also give you insights that will help you to sustain your study in school.
Which function is positive for the entire interval [-3, -2]
We are given 4 graphs.
We need to find the function graph which is positive of the entire interval [-3, -2]
It is a closed interval. So it is inclusive of -3 and -2
In these interval the graph of y value must be in positive region.
By looking at the graph, the graph B has positive y-values in the entire interval [-3, -2]
Therefore, the answer is Graph B)
From the answer and question examples above, hopefully, they are able to guide the student resolve the question they had been looking for and take notice of every thing stated in the answer above. You could actually then have a discussion with your classmate and continue the school learning by studying the question altogether.
