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.

welll its a very hard question but ill

step-by-step explanation:

first you take the 6 dollars and add 10 to it then add the 50 to that then multiply by 8 with xy and your answer will be
