What is the point of tangency – no calculus, please

Problem Two lines intersect the graph . The secant line intersects the graph at point A and B and the tangent line which is parallel to the secant, touches the graph at point E. You can read the coordinates of A and B from the graph but not E. What are the coordinates of E?

Matching function graphs and tables

A function can be represented by graphs, tables and equation. Each of these representations of function have their own strengths and limitations. So an indicator of understanding of function is knowledge of the link between representations. The following problem tests your understanding of function represented in graphs and tables. In the question, the graph is not on
