We know that
the quadratic function in vertex form is--------------> y=a*(x-h)²+k
we have
f(x)=x²<span>+14x+40
y=</span>x²+14x+40
We can convert to vertex form by completing the
square on the right hand side
y-40=x²+14x
y-40-49=x²+14x-49------> subtract 49 on BOTH sides to
preserve the equality
y-40=(x²+14x+49)-49
y=(x²+14x+49)-49+40---------> y=(x+7)²-9
the answer is
the quadratic function in vertex form-----------> y=(x+7)²-9
<span>the vertex is the point (-7,-9)
</span>

Answer:
a is the answer
Step-by-step explanation:
I'm sorry I'm not entirely sure. But I think -2 and 4. If it's not multiple choice I say -2.
Answer:
0.3, 0.32, 0.321, 0.345
Step-by-step explanation:
The maximum number of decimals shown in the series is 3.
Therefore, let's rewrite all the numbers with three decimal places.
0.32, 0.321, 0.3, 0.345 can be written as
0.320, 0.321, 0.300, 0.345
Now, we can easily compare the numbers and we can conclude:
0.300 < 0.320 < 0.321 < 0.345
Hence, the smallest to largest order is:
0.3, 0.32, 0.321, 0.345
