Answer:
f(x) = -2x² + 2
Step-by-step explanation:
If you remember the y = x² parent graph, you will be able to derive your equation from visualization.
The vertex of this graph would be at (0, 2), so your degree coefficient would be negative. Your y-intercept would also be at (0, 2). Since both 1 and -1 are included, you can tell it is a parabola, and hence the 3rd option is your answer.
They would have made $9 million more than last year.
Answer:
(1/2, 6).
Step-by-step explanation:
Turning points in a graph may exist whenever the derivative equals 0. Hence, let’s differentiate and then solve our function.
We have:

Take the derivative of both sides with respect to x:

Simplify:

We will now set this equal to 0 and solve for x. Hence:

Hence, the graph turns at x=1/2. This is the x-coordinate.
Then it follows that the y-coordinate will be:

Hence, our coordinate Is (1/2, 6).
Answer:
5(7 + 6s - 9t)
