Answer the questions about the following functions.
f(x) = 14^2/x^4 + 49
(a) Is the point (sqrt 7,1) on the graph of f?
(b) If x=1, what is f(x)? What point is on the graph of f?
(c) If f(x)=1, what is x? what point(s) are on graph of f?
(d)What is the domain of f?
(e) list the xintercepts if any
(f) list the yintercepts if any

Fix the typo
(d) the domain is all real numbers, since x^2+49 is never zero
The rest should be easy. Come back if you get stuck, and show how far you got.
