Question: Draw the graph of y=3. Answer: The graph of y = 3 is a line parallel to the x-axis. ..
Question: Draw the graph of y=3. Answer: The graph of y = 3 is a line parallel to the x-axis. ..Examples:
(1) 2x 2 -1 = 0 (2) x 2 -5x+7 = 0 The solution to quadratic equations can be found using various techniques. One of them being, graphs..
Functions Limits and Continuity
The concept of limits leads to define and describe continuity and derivative of the function. The continuity of a function has practical as well as theoretical importance. We plot graphs by taking the values generated in the laboratory or collected in the field. We connect the plotted p..

Following are the test for Functions
(a) (i) The relation should be one-one or many-one, and (ii) Every first element is mapped which means that every pre-image should have an image. (b) For graphs: Draw a line parallel to the y-axis. If it cuts the graph only in one point, then the graph represents a fu..

Tutor is the BEST. I have learned a lot from her. I never thought algebra will become my favourate subject. All because of Tutor Vista.
This tutor was excellent. very clear on all of the problems. I would like to have more tutoring from Tutor Vista
Very good, Tutor was clear and guided me through the whole algebra problems
This Tutor Vista is GREAT! loved this session, it helped me heaps.
Looking for More Help!
