We are asked to determine what happens to the values of
as
approaches
using values of
less than
AND using values of
greater than
.
<span>Observe from the graph that as </span>
approaches
from the left or the right, the values of
increase without bound.
Therefore, we know the following.
Answer:
B
Step-by-step explanation:
Given a quadratic function in standard form
y = ax² + bx + c ( a ≠ 0 )
• If a > 0 then the graph opens upwards
• If a < 0 then the graph opens downwards
y = x² + 5x + 6 ← is in standard form
with a = 1 > 0
The graph therefore opens upward
