Which function represents a reflection of f(x) = Three-sevenths(2)x over the x-axis?

g(x) = –Three-sevenths(2)x
g(x) = Three-sevenths(–2)x
g(x) = Three-sevenths (one-half)–x
g(x) = Seven-thirds(2)–x

Given:

The given function is

We need to determine the reflection of f(x) over the x - axis

Reflection over x - axis:

The translation rule to reflect over the x - axis is given by

Thus, applying the rule, the function becomes

Multiplying both sides of the equation by -1, we have;

This can be written as

Hence, the reflection of the function over the x - axis is

Thus, Option A is the correct answer.

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

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
