Answer:
In BOLD.
Step-by-step explanation:
f(x) = (x - 1)(x + 7)
Convert to vertex form.
= x^2 + 6x - 7
= (x + 3)^2 - 9 - 7
= (x = 3)^2 - 16
So the vertex is at (-3, -16)
Also, as the vertex is a minimum the graph is increasing on interval x > -3.
From the graph we see:
The graph is positive on the interval
where x < -7 and x > 1.
- and negative where
-7 < x < 1.
