Answer:
1st option
Step-by-step 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 = > 0
then f(x) opens up and has a minimum
Answer:
Option A, open up and have a minimum
Step-by-step explanation:
<u>Step 1: Determine if it opens up or down</u>
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

you can check in your calculator.
anyhow, to get the "recurring decimal to fraction", you start by setting to some variable, "x" in this case, then move the repeating part to the left of the point by multiplying it by some power of 10, and then do the equating.
