Answer:
The vertex is the point (-1,11). is a maximum
Step-by-step explanation:
we know that
The equation of a vertical parabola in vertex form is equal to
where
(h,k) is the vertex
a is a coefficient
if a > 0 the parabola open upward and the vertex is a minimum
if a < 0 the parabola open downward and the vertex is a maximum
we have
Convert to vertex form
Complete the square
Factor the leading coefficient
Rewrite as perfect squares
The vertex is the point (-1,11)
The coefficient a=-5
so
a < 0 the parabola open downward and the vertex is a maximum
How many times a particular number is a zero<span> for a given polynomial. For example, in the polynomial function f(x)=(x–3)4(x–5)(x–8)2, the </span>zero<span> 3 has </span>multiplicity<span> 4, 5 has </span>multiplicity<span> 1, and 8 has </span>multiplicity<span> 2. Although this polynomial has only three </span>zeros<span>, we say that it has seven </span>zeros<span> counting </span><span>multiplicity</span>

</h3>
Step-by-step explanation:
<h3>to understand this</h3><h3>you need to know about:</h3>
- inequality
- solving inequality
- PEMDAS
<h3>given:</h3>
5 ≤ - 3x- 3 ≤ 10
<h3>to solve:</h3>
x
<h3>let's solve:</h3>
few notes about inequality
the direction of the inequality doesn't change if you
- Add (or subtract) a number from both sides
- Multiply (or divide) both sides by a positive number
- Simplify a side
the direction of the inequality does change
if you
- Multiply (or divide) both sides by a negative number
- Swapping left and right hand sides
