Question

Find the x-intercept of the function x² - 2.

(0, 0)
(0, -2), (0, 2)
(2, 0), (-2, 0),
$(\sqrt{2}, 0), (- \sqrt{2}, 0)$

hint Hint:

To find the x-intercept, substitute in 0 for y and solve for x.

The correct answer is: $left parenthesis square root of 2 comma 0 right parenthesis comma left parenthesis negative square root of 2 comma 0 right parenthesis$

To find the x-intercept, substitute in 0 for y and solve for x.
$x squared minus 2 equals 0 x squared equals 2 x equals plus-or-minus square root of 2$
