Answer:
E
Step-by-step explanation:
For the equation F(x) = ax² + bx + c we have:
- maximum value if a<0
- minimum value if a>0
F(x) = -3x² + 18x + 3 ⇒ a = -3, b = 18
a < 0 ⇒ the function has a maximum value
Quadratic function has the maximum value (or minimum) at vertex of its parabola.
The maximum value is k at x=h where:
and k = F(h)

Therefore:
<h3>
The function has a maximum value of 30 at x = 3</h3>
Answer:
Step-by-step explanation:
the polynomial function is; (x - i)(x-2)(x+2)
80% of 7.5 is 6.
so if he travelled 80% further, it would be 7.5+6 which is
13.5
Answer:
depends on how many miles you can go on 1 mile.
