Determine the x-intercept(s) of the rational function: <br> f(x) = (x ^ 2 - 16)/(x ^ 2 - 2x - 3)
elena55 [62]

Answer:

(-4,0) and (4,0)

Step-by-step explanation:

The x-intercepts occur for values of x where f(x) = 0.

f(x) = 0 when the nominator (x^{2}  - 16) = 0.

x^{2} -16 is a difference of squares,
so you can factor it as (x + 4)(x – 4)

When x = –4 or x = 4, the nominator is 0, and f(x) = 0
