First make x the subject of the relation:-

f(x) = 2x - 4

2x = f(x) + 4

x = (f(x) + 4) / 2

Now replace x by the inverse f-1(x) and f(x) by x :-

f-1(x) = (x + 4) / 2

The relationship between the input values (x) and the output values (y) is :'y is one less than a quarter of x'

sattari [20]

An equation in the form of y is y = x/4 - 1

<h3>An equation in the form y = ...</h3>

The statement is given as:

'y is one less than a quarter of x'

A quarter of x means x/4

So, we have:

y = x/4 - 1

Hence, an equation in the form of y is y = x/4 - 1

<h3>Number sentences</h3>

From the question, we have:

x = -4, -2,0, 2 and 4

Substitute these values in y = x/4 - 1

-4/4 - 1 = -2

-2/4 - 1 = -1.5

-0/4 - 1 = -1

2/4 - 1 = -0.5

4/4 - 1 = 0

The above represents the number sentences

Enter the coordinates of the vertices of r(180,0) and t(3,-2) (QRST) will give crown

Viktor [21]

Answer:

Step-by-step explanation:

From the graph attached,

Coordinates of the vertices are,

Q(1, 3), R(3, -3), S(0, -2) and T(-2, 1)

Following the rule of translation by 3 units to the right and 2 units down $T_{(3, -2)}$

(x, y) → (x+3, y-2)

Q(1, 3) → Q''(4, 1)

R(3, -3) → R"(6, -5)

S(0, -2) → S"(3, -4)

T(-2, 1) → T"(1, -1)

Following rule $r_{(180,\text{O})}$ (rotation of a point by 180° about the origin) will give the image points,

(x, y) → (-x, -y)

Q"(4, 1) → Q'(-4, -1)

R"(6, -5) → R'(-6, 5)

S"(3, -4) → S'(-3, 4)

T"(1, -1) → T'(-1, 1)
