Question

A 2-column table with 6 rows. The first column is labeled x with entries negative 2, negative 1, 0, 1, 2, 3. The second column is labeled f of x with entries negative 10, negative 8, negative 6, negative 4, negative 2, 0.
Which is an x-intercept of the continuous function in the table?

(0, –6)
(3, 0)
(–6, 0)
(0, 3)

Answer 1

An x-intercept has f(x)=0. From the table f(3)=0, so the x-intercept is (3, 0).
