Need help or i fail and loose my gf

Wow that's a big threat. Don't want you to fail or loose your girlfriend so I'll help you out...
We know that x is 3 and y is -6 so replace the x and y with their corresponding numbers in the equation: 36x-8. So...
36(3) - 8
Multiply 36 and 3 together:
108 - 8
Square -6
108 - 8(36)
Multiply -8 by 36
108 - 288
Subtract them and you get...
-180
Hope this helped! And tell your gf not to break up with you since you got this question right lol

The statements about the function that are true are
- The vertex of the function is at (–3,–16).
- The graph is increasing on the interval x > –3.
- The graph is positive only on the intervals where x < –7 and where x > 1.
The equation of the graph is given as
f(x) = (x - 1)(x + 7)
The graph of the function is added as an attachment
On the graph, we have
Vertex = (-3, -16)
This is so because the graph has a minimum point of (-3, -16)
Also, the graph crosses the x-axis at x = 1 and x = -7
This means that the graph is positive at x >1 and x >-7
Because the vertex is a minimum, the graph is increasing at the left of its symmetry i.e. x > -3
