Find the range of the function for the fiven domain. f(x)= 3x-8; {-2, -1, 0, 1, 2}

1 answer:

7 0

f(x)= 3x-8

x = -2, f(x)= 3(-2) -8 = -6 - 8 = -14
x = -1, f(x)= 3(-1) -8 = -3 - 8 = -11
x = 0, f(x)= 3(0) -8 = 0 - 8 = -8
x = 1, f(x)= 3(1) -8 = 3 - 8 = -5
x = 2, f(x)= 3(2) -8 = 6 - 8 = -2
Domain {-2, -1, 0, 1, 2}
Range: {-14, -11, -8, -5, -2}

answer
Range: {-14, -11, -8, -5, -2}

At the equilibrium price p, we can solve for the quantity of goods x :

demand = supply

5200 - 0.0005x = 2800 + 0.0003x

2400 = 0.0008x

x = 3,000,000

With this quantity of goods, the equilibrium price is

p = 5200 - 0.0005 (3,000,000)

p = 5200 - 1500

p = 3700

Answer: $ 2.20

Step-by-step explanation: 31.80-18.60= 13.20

13.20 divided by 6= 2.20

——————-

2.20 x 6= 13.2

13.20+ 18.60= 31.80

Which value of X makes the quotient of (5x^5+90x^2-135x)/(x+3) undefined

faust18 [17]

Answer:

b) - 3

Step-by-step explanation:

If x = -3 , then

x + 3 = -3 + 3 = 0

So, denominator would become 0. So , anything divided by 0 is undefined

What set of reflections and rotations would carry rectangle ABCD onto itself? Parallelogram formed by ordered pairs A at negativ

Hoochie [10]

Answer:

Option (4).

Step-by-step explanation:

Let's take the coordinates of point A for the set of reflections and rotations given in the options.

Option (1). Rotate 180° → A(-4, 1) becomes (4, -1)

Reflect over x-axis → (4, -1) becomes (4, 1)

Reflect over the line y = x → (4, 1) becomes A'(1, 4)

Therefore, point A will not overlap itself after the number of transformations given.

Option (2). Reflect across x-axis → A(-4, 1) will become (-4, -1)

Rotate 180° → (-4, -1) becomes (4, 1)

Reflect over the x-axis → (4, 1) becomes A'(4, -1)

Therefore, point A(-4, 1) doesn't overlap A'(4, -1).

Option (3). Rotate 180° → A(4, 1) becomes (-4, -1)

Reflect over the y-axis → (-4, -1) becomes (4, -1)

Reflected over y = x → (4, -1) becomes (-1, 4)

So the point A(4, 1) becomes A'(-1, 4) after the set of reflections,

Option (4). Reflect over the y axis → A(-4, 1) becomes (4, 1)

Reflect over the x-axis → (4, 1) becomes (4, -1)

Rotate 180° → (4, -1) becomes A'(-4, 1)

Therefore, point A will overlap itself following the set of transformations.
