What's the domain and range of thr dots plotted on the graph?

M the table below represents a linear function f(x) and the equation represents a function g(x): x f(x)−1 −50 −11 3g(x)g(x) = 2x − 7part a: write a sentence to compare the slope of the two functions and show the steps you used to determine the slope of f(x) and g(x). (6 points)part b: which function has a greater y-intercept? justify your answer. (4 points)

Rewrite the following quadratic functions in intercept or factored form. show your work. f(x) = 3x^2 - 12

How is this equation completed? i cannot find any examples in the book.
