Answer: The value of polynomial function at -1 is 0 and the option d is correct.
Explanation:
The given function is,

We have to value of polynomial function at -1. It means we have to find f(-1).
Put x=-1 in the given function.




Therefore option d is correct and the value of polynomial function at -1 is 0.
for the lines k (x) = (- 9 / 5) x + (5 / 2) and h (x) = (2 / 5) x - (7 / 6), the solution for x will be 5 / 3 and y will be - 1 / 2.
We are given the two lines:
k (x) = (- 9 / 5) x + (5 / 2)
h (x) = (2 / 5) x - (7 / 6)
At the intersection of the two lines, we get that:
(- 9 / 5) x + (5 / 2) = (2 / 5) x - (7 / 6)
(2 / 5) x + (9 / 5) x = (5 / 2) + (7 / 6)
(11 / 5) x = 11 / 3
3 x = 5
x = 5 / 3
y = (2 / 5) (5 / 3) - (7 / 6)
y = 2 / 3 - 7 / 6
y = - 1 / 2
Therefore, we get that, for the lines k (x) = (- 9 / 5) x + (5 / 2) and h (x) = (2 / 5) x - (7 / 6), the solution for x will be 5 / 3 and y will be - 1 / 2.

The general eaquation of a parabola in terms of its vertex is:
y = a(x - h)^2 + k
where the vertex point is (h, k)
therefore, an equation of a parabola with vertex (1, -2) is:
y = 5(x - 1)^2 - 2
