Determine if this is a function.

Mathematics
1 answer:
Kruka [31]3 years ago
6 0

Answer: This is <u>not</u> a function

Why not?

The input x = 2 leads to more than one output. In this case, it leads to y = 20 and y = 40 simultaneously. This is the reason why we don't have a function. A function is only possible if each input x leads to exactly one y output.

Put another way: we cannot have x repeating any values if we want a function.

Side note: We could have y repeat however. So it's possible to have a function with the two points (1,5) and (3,5).

Describe how the graph of y= x^2 can be transformed to the graph of the given equation.
AnnyKZ [126]

Answer:

We conclude that the graph y = x² can be transformed into the graph of the given equation y = (x - 12)²+3 by shifting the graph of y = x² right 12 units and then up 3 units.

Hence, option D is true.

Please check the attached graph.

Step-by-step explanation:

Given the parent function

y = x²

Given the transformed function

y = (x - 12)²

Horizontal Translation:

The horizontal translation of y = x² is of the form

f(x-h)

so y = y = (x - 12)² means y = x² is shifted 12 right.

Vertical Translation:

y = x²

Then y = x² + b is a vertical translation of y = x²

if b > 0, then y = x² + b is the graph of y = x² 'b' units up.

if b < 0, then y = x² + b is the graph of y = x² 'b' units down.

Thus, y = x² + 3 means the graph y = x²  is vertically shifted up by 2 units.

Please check the attached graph.

  • The blue graph is representing the graph of y = x².
  • The red graph is representing the graph of y = (x - 12)²+3

Therefore, the graph y = x² can be transformed into the graph of the given equation y = (x - 12)²+3 by shifting the graph of y = x² right 12 units and then up 3 units.

Hence, option D is true.

¿Como encontrar los dos puntos de una gráfica?
blagie [28]
Si estas haciendo una linea recta vas a necesitar dos puntos. Los encuentras poniendo un numero por x en la formula para que te de un numero, y. Y te va dar (x, y). Lo haces otravez con otro valor de x y ese te va dar (x2, y2). Y luego los conectas con una linea.

The bakery Delicias Culinarias sells wedding cakes that are shaped like cylinders with heights and diameters shown below
Art [367]

Answer:

The icing cover refers to the surface area of the cake.

Surface area of cylinder = 2*pi*r^2 + 2*pi*r*h

Surface area of cylinder without bottom area = pi*r^2 + 2*pi*r*h

Subtracting the areas, we have Difference = 254.5 in2

Step-by-step explanation:

The icing cover refers to the surface area of the cake.

The surface area of a cylinder is given by:

S = 2*pi*r^2 + 2*pi*r*h

As we don't need to cover the bottom of the cake, we can use the following formula:

S = pi*r^2 + 2*pi*r*h

So for the bigger cake, the radius is 7 inches and the height is 8 inches, then we have:

S1 = pi*7^2 + 2*pi*7*8 = 505.7964 in2

The smaller cake has a radius of 4 inches and height of 8 inches, so:

S2 = pi*4^2 + 2*pi*4*8 = 251.3274 in2

To find how much area will be covered more for the bigger cake, we just need to find the difference of the bigger cake area by the smaller cake area:

Difference = S1 - S2 = 505.7964 - 251.3274 = 254.469 in2

Rounding to nearest tenth, we have Difference = 254.5 in2
