Answer 1

1st option

Explanation:

given a quadratic function in standard form

f(x) = ax² + bx + c ( a ≠ 0 ) , then

• if a > 0 , the function opens up and has a minimum

• if a < 0 , the function opens down and has a maximum

here a =
`(1)/(2)` > 0

then f(x) opens up and has a minimum

Answer 2

Option A, open up and have a minimum

Explanation:

Step 1: Determine if it opens up or down

Since the value of a is 1/2 which means that it's positive which also means that it opens up. When a parabola opens up, that means that it has a minimum.

The picture attached to this answer shows an example of how a graph would look when using this equation. If a was -1/2 then the parabola would be facing down and would have a maximum.

Answer: Option A, open up and have a minimum
