Question

Identify all asymptotes and intercepts:

a) f(x) = 1/x^2-4

b) f(x) = x-4/x+2

Answer 1

the intercept is where it crosses the y-axis so x is 0

Answer 2

so PLUG IN 0 for x and that answer should be the y-intercept

Answer 3

if you set the function equal to zero you will get the X-intercepts

Answer 4

the asymptotes are when the denominator equals zero so set the denominator equal to zero and solve for x
