Given the functions ƒ(x) and g(x), which of the following statements is true? x -2 -1 0 1 2 ƒ(x) -3 3 5 3 -3 g(x) = -x2 + 4x ƒ(x

Morgarella [4.7K]

Answer:

The correct option is 1.

Step-by-step explanation:

From the given table is notices that the function f(x) is a downward parabola.

The maximum value of f(x) is 5 at x=1.

The function g(x) is

$g(x)=-x^2+4x$

vertex of the parabola is

$(\frac{-b}{2a}, g(\frac{-b}{2a}))$

$(\frac{-4}{2\times 1}, g(\frac{-4}{2\times 1})$

$(2, g(2))$

Put x=2.

$g(x)=-2^2+4(2)=4$

Therefore the vertex of g(x) is (2,4). The vertex of a downward parabola is the maximum point of the function.

Therefore ƒ(x) has the greater maximum. Option 1 is correct.

You visit 3 different stores that sell Takis. Store X has 3 bags of Takis for $3.04. Store Y has 5 bags of Takis for $3.60. Stor

pychu [463]

<em>store y has the better buy.</em>

store x -- 3.04 ÷ 3 = $1.01 per bag

store y -- 3.60 ÷ 5 = $0.72 per bag

store z -- $0.78 per bag

store y cost the least so it is the best option.

Gina has 440 yards of fencing to enclose a rectangular area. Find the dimensions of the rectangle that maximize the enclosed are

podryga [215]

Answer:

<h3>THerefore, the area would be 12,100 square yards</h3>

Step-by-step explanation:

Let the length be x and the width be y

The perimeter of a rectangle is give as ; 2 ( L + B) , that is

We know the perimeter formula would be 440=2x+2y. And the area will be A=x*y

We can to take the derivative of the area formula to find where it is a max but we must first substitute something in from the first formula so we only have one variable.

440-2x=2y

220-x=y

A=(x)*(220-x)

A=220x-x^2

Now we take the derivative:

A'=220-2x (set equal to 0 and solve)

0=220-2x

2x=220

x=110

Then when we plug this into the perimeter formula, we can solve for y

440=2x+2y

440=2(110)+2y

440=220+2y

220=2y

y=110

So both the length and width are 110 yards, and the area would be 12,100 square yards

<h3>THerefore, the area would be 12,100 square yards</h3>

Will Mark brainliest if correct. Will report if not correct.

Ksju [112]

Answer:

Looks like the scale factor is 1/3.

Step-by-step explanation:

<em>(In this dilation, the green image is polygon ABCDE, and the red image is polygon A'B'C'D'E'. The red image is the resulting image after said dilation.)</em>

A scale factor greater than one enlarges an image, and a scale factor between zero and one shrinks an image, so that rules out options 2 (SF = -3) and 3 (SF = 3).

A negative scale factor would end up in an image opposite the center of enlargement, so that eliminates option 4 (SF = -1/3).

So that means that the scale factor is option 1 (SF = 1/3)!
