Answer:

1) Function; Linear Function (y=x)

2) Function; Exponential Function (y=bˣ)

3) Not a function.

Step-by-step explanation:

So, let's go through each table of values. I'm also going to graph them (see attached graphs) because it will make things simpler and provide a visual.

First, also recall what the definition of a function is. A function is a function if and only if an x only has <em>one</em> distinct y-value. No x can have two or more y-values. For instance, (1,2) and (1,3) is <em>not</em> a function between the x repeats. So, let's go through the choices:

1)

We have the table as shown. Let's plot the points. See TABLE 1:

First, there are no repeating x-values, so we can be sure that this is indeed a function.

Looking at the graph, we can see that this resembles a linear graph. So, the parent function of this is a line.

The parent function of a line is:

y=x

So, table 1 is associated with a linear function.

2)

Let's again plot the points. See TABLE 2.

Again, there are no repeating x-values, so this is also a function.

Looking at the graph, this resembles an exponential function. The function increases slowly at first but starts increasing increasingly fast. The parent function is thus an exponential function.

So, table 2 is associated with an exponential function.

3)

First, notice how all the x-coordinates are repeating. And since they do <em>not</em> equal the same thing, this is not a function.

Table 3 is not a function and so has no corresponding family function.

Note that a function has one x-value assigned to one y-value. If an x-value has more then one y-value then it is not a function.

Question 1:

No x value is given more then y value so this is a function.

If we plot the points, it goes up in a steady line. Thus, this makes it a linear function since it has one slope.

Question  2:

No x value is given more then y value so this is a function.

If we plot the points, it starts going up at a slow pace. After a while, the points go up at a fast pace making it where it doesn't have one slope. Since its a curve like function, it is exponential.

Question 3:

All x values are the same but with different y-values. Thus, makes this not a funtion.

Best of Luck!

Answer:

x= 3.57

Step-by-step explanation:

32 ( x + 2.5) = 114.24

32* x + 32* 2.5= 114.24

32x + 80= 114.24

        -80      -80

32x= 114.24

/ 32    /32

x= 3.57

for the part that says convince me, we can use the eqution

/= divide

Answer:

to find the scale factor we just need to take one of the side lengths of the larger figure, 20, and divide it by the corresponding side length in the smaller figure, 8. Therefore 20/8 is correct

Ms. Smith made 30 cupcakes. She put vanilla icing 1/3 of the cupcakes and chocolate icing on 1/2 of the remaining cupcakes. The
Anna007 [38]

Answer:

10

Step-by-step explanation:

Let's break it down:

  • We need to remove the third of ALL the cupcakes that got Vanilla Icing. 1/3 of 30 is 10. This means you need to subtract 10 from the original 30.
  • This leaves 20 left
  • Half of the remaining 20 will get Strawberry Icing.
  • 1/2 of 20 is 10 (the amount getting Strawberry Icing)
