Suppose f(x) = 4x - 8 with f(x) = y. What is/are the vertical intercept(s) of f? If there is more than one, enter your answers as a comma-separated list. (2,0) Incorrect. What is/are the horizontal intercept(s) of f? If there is more than one, enter your answers as a comma-separated list.

For each of the following questions, if there is more than one solution, enter all solutions as a comma-separated list, like "1, 3". Consider the function f(x) = 5(x + 8) - 6. What is the vertical intercept of f? What are the horizontal intercepts (or "roots") of f? Consider the function g(x) = x(7 - 2x)(9 - 2x). What is the vertical intercept of g? What are the horizontal intercepts (or "roots") of g?
