Question

What are the x-intercept of the graph y=(x-2)(x-6)

Answer 1

The function crosses the x-axis at x = 2

y = (2-2)(2-6) = (0)(-4) = 0

Answer 2

x =2 and x = 6 are the x-intercepts

Explanation:

The x -interepts mean the value of x when y=0

so

y = 0 = (x - 2)(x - 6)

Here if we solve for x, we solve the x-intercepts.

0 = (x - 2) or 0 = (x - 6)

x = 2 or x = 6
