Answer:
Vertex form: 
Standard form: 
Step-by-step explanation:
A quadratic function in vertex form is
where
is the vertex.
We are given
.
Let's plug that in:
.
Now let's find
.
We will use the
-intercept
to find
.






So the function in vertex form is:
.
In standard form, we will have to multiply and combine any like terms.
Let's do that:



Answer: It is 2/3
Step-by-step explanation:
x + 3, x > -3 is the piece which will be included in the given function f(x) = [ x + 3 ]. This can be obtained by removing modulus and finding the value for x.
<h3>Which piece will the function include?</h3>
Given that,
f(x) = [ x + 3 ] which is an absolute value function.
Therefore,
| x+3 | > 0
By removing the modulus,
x+3 > 0
x > - 3
Hence x + 3, x > -3 is the piece which will be included in the given function f(x) = [ x + 3 ].
