We make use of the fact that a function's y value is equal to zero when it intersects the x-axis.
Since f ( x ) = x 2 + 6 x + 5 , we can say that:
y = x 2 + 6 x + 5
When the graph of this function intersects with the x-axis, then y=0.
Then, we have:
0 = x 2 + 6 x + 5 Now we can find x's value.
=> 0 = ( x + 1 ) ( x + 5 )
- 1 = x = - 5
This means that the x-intercepts are: (-1,0) and (-5,0)
