Answer:
<h2>2. D. 64</h2><h2>5. B. 1, -3/2</h2><h2>6. C. 0, 2</h2>
Step-by-step explanation:



1 400 000 000 000 000 000 000 km = 1.4 * 10^21 km
Your answer would be ( -12/5 x + 2 )
First,
We are dealing with parabola since the equation has a form of,

Here the vertex of an up - down facing parabola has a form of,

The parameters we have are,

Plug them in vertex formula,

Plug in the
into the equation,

We now got a point parabola vertex with coordinates,

From here we emerge two rules:
- If
then vertex is max value - If
then vertex is min value
So our vertex is minimum value since,

Hope this helps.
