How do you find the quadratic function with vertex (-2,5) and point (0,9)?
Anastaziya [24]

Answer: y = (x +2)² + 5

<u>Step-by-step explanation:</u>

y = a(x - h)² + k <em>where "a" is the leading coefficient and (h, k) is the vertex</em>

Since we don't know "a", we need to plug in the point (x, y) and the vertex (h, k) to solve for "a":  (x, y) = (0, 9) and (h, k) = (-2, 5)

y = a(x - h)² + k

9 = a(0 - (-2))² + 5

9 = a(0 + 2)² + 5

9 = a(2)² + 5

<u>-5 </u>   <u>          -5 </u>

4  =  a(4)

<u>÷4 </u>   <u> ÷4   </u>

 1 = a

Next, plug in "a" and the vertex (h, k):

y = a(x - h)² + k

y = 1(x +2)² + 5

y = (x +2)² + 5

What is the leading coefficient of a third degree polynomial function that has an output of 1,272 when x=2, and has zeros of −6,
Gre4nikov [31]

Answer:

<em>The leading coefficient is 3</em>

Step-by-step explanation:

<u>Polynomials</u>

Given the roots of a polynomial x1,x2,x3, it can be expressed as:

p(x)=a(x-x1)(x-x2)(x-x3)

Where a is the leading coefficient.

We are given the roots x1=-6, x2=7i, x3=-7i, thus:

p(x)=a(x+6)(x-7i)(x+7i)

Operating the product of the conjugated imaginary roots:

p(x)=a(x+6)(x^2+49)

Knowing p(2)=1,272 we can find the value of a

p(2)=a(2+6)(4+49)=1,272

Operating:

a(8)(53)=1,272

424a=1,272

Solving:

a=1,272/424

a=3

The leading coefficient is 3
