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 x-intercepts if any
(f) list the y-intercepts if any

  • College algebra -

    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.
