Use the function f(x) = −16x^2 + 22x + 3 to answer the questions.

vaieri [72.5K]

Answer:

see below

Step-by-step explanation:

f(x) = −16x^2 + 22x + 3

Factor out the negative

f(x) = -( 16x^2 -22x -3)

= -(8x+1)(2x-3)

Find the x intercepts

Set y = 0

0 = -(8x+1)(2x-3)

Using the zero product property

8x+1 =0 2x-3 = 0

8x = -1 2x = 3

x = -1/8 x =3/2

The x intercepts are ( -1/8, 0) and ( 3/2, 0)

The end behavior

-16 x^2 is the dominate term

Let x →-∞

f(-∞) = -16 (-∞)^2 = -16 (∞) = -∞

As x goes to negative infinity y goes to - infinity

Let x →∞

f(∞) = -16 (∞)^2 = -16 (∞) = -∞

As x goes to infinity y goes to - infinity

We know this is a downward facing parabola a < 0 and this is a quadratic

We have the x intercepts

We can find the axis of symmetry from the zeros

(-1/8+ 3/2) /2 = (-1/8 + 12/8)/2 = (11/8)/2 = 11/6

The axis of symmetry is x = 11/16

Using the axis of symmetry and the equation, we can find the maximum point

y = -(8*11/16+1)(2*11/16-3) = 169/16

The vertex is at (11/16, 169/16(

Compare the function with the parent function. Without graphing, what are the vertex, axis of symmetry, and transformations of t

Alborosie

Answer:

The parent function is: y = x

First, here we have two types of transformations, and we could define them in a general way as:

if we start with a function f(x)

Vertical dilation/contraction: A vertical dilation/contraction of scale factor A (A is always positive) is written as:

g(x) = A*f(x)

Vertical translation:

We can write a vertical translation of A units upwards as:

g(x) = f(x) + A

And a vertical translations of A units down can be written as:

g(x) = f(x) - A.

In this case, the transformations are:

first, a dilation of scale factor 8.

Then a translation down of 21 units

then another translation down of 7 units.

y = 8*X - 21 - 7

y = 8*x - 28.

As this is a linear equation, there are no axis of symmetry, we only could have a line of symmetry along the same line y = 8*x - 28

Again, as this function is a linear equation there is no vertex.

The width of park is $\frac{7}{4}$ miles.

Step-by-step explanation:

Given,

Area of park = $\frac{7}{8}\ square\ miles$

Length of park = $\frac{4}{8}\ mile$

Let,

w be the width of park.

Area = Length * Width

$\frac{7}{8}=\frac{4}{8}w$

Multiplying both sides by $\frac{8}{4}$

$\frac{8}{4}*\frac{7}{8}=\frac{8}{4}*\frac{4}{8}w\\\frac{7}{4}=w\\w=\frac{7}{4}\ mile$

The width of park is $\frac{7}{4}$ miles.
