Question

the graph of f(x)=1/x^2-c has a vertical asymptote at x=3. find c

Answer 1

the vertical asymptote occurs when x^2 - c is 0

since x = 3 is the vertical asymptote, we can plug this in to solve for c

x^2 - c = 0

3^2 - c = 0

c = ??

Answer 2

c= 3^2?

Answer 3

or c = 9, the simplified form
