Can somebody ASAP help me in this thank you sm:)

When only separate discreet points are graphed it is called?

Express in the simplest form: (x^2+9x+14/x^2-49) / (3x+6/x^2+x-56)

Consider the following equation. 1/2x^3+x-7=-3sqrtx-1 approximate the solution to the equation using three iterations of successive approximation. use the graph below as a starting point. a. b. c. d.
