Identifying and Graphing Sequences: lesson 4-1
goldfiish [28.3K]

Answer:

1) Domain: {   1,2,3,4,5,6}

Range: {12,24,36,48,60,72}

2) First four terms are: 2,5,8,11

3) First four terms are: 8,13,20,29

4) First four terms are: 0,0,2,6

5) First four terms are: 0,1,1.41,1.73

Step-by-step explanation:

1.

n       1      2     3     4      5      6

f(n)    12    24    36   48    60    72

Domain: {   1,2,3,4,5,6}

Range: {12,24,36,48,60,72}

Write first four terms of each sequence

2) f(n)=3n-1

Put n = 1, 3(1)-1 = 3-1 = 2

Put n = 2, 3(2)-1 = 6-1 = 5

Put n = 3, 3(3)-1 = 9-1 = 8

Put n = 4, 3(4)-1 = 12-1 = 11

So, First four terms are: 2,5,8,11

3) f(n)=n^2+2n+5

Put n = 1, (1)^2+2(1)+5= 1+2+5 = 8

Put n = 2, (2)^2+2(2)+5 = 4+4+5= 13

Put n = 3, (3)^2+2(3)+5 = 9+6+5 = 20

Put n = 4, (4)^2+2(4)+5 = 16+8+5 = 29

So, First four terms are: 8,13,20,29

4) f(n)=(n-1)(n-2)

Put n = 1, (1-1)(1-2) = 0(-1) = 0

Put n = 2, (2-1)(2-2) = 1(0) = 0

Put n = 3, (3-1)(3-2) = 2(1) = 2

Put n = 4, (4-1)(4-2) = 3(2) = 6

So, First four terms are: 0,0,2,6

5) f(n) = \sqrt{n-1}

Put n=1 \sqrt{1-1}=\sqrt{0}=0

Put n=2 \sqrt{2-1}=\sqrt{1}=1

Put n=3 \sqrt{3-1}=\sqrt{2}= 1.41

Put n=4 \sqrt{4-1}=\sqrt{3}=1.73

So, First four terms are: 0,1,1.41,1.73

Andrei [34K]
A) Gavin’s drinks altogether cost £9.00
1.50+2.50x3
=1.50+7.50
=£9.00
b) Lian gets back £3.50
1.50+2.00+3.00
=6.50

10.00-6.50=£3.50

I GIVEEEEE BRASINLILST
Zina [86]

Answer:

<em>Answer: Choice G.</em>

Step-by-step explanation:

<em>Dilations</em>

Suppose a point P(x,y) is dilated across the origin, that is, the origin is the center of dilation, by a scale factor k.

The image of P is P' whose coordinates are P'(kx,ky).

If an image is formed by several points and each one is dilated by the same factor, then:

If |k| > 1, the image maps to a stretched or larger image.

If |k| < 1, the image maps to a shrunk or shorter image.

We have a hexagon graphed on a coordinate grid. The hexagon is dilated to create a larger hexagon. This means k must be greater than 1 and it should multiply each original coordinate (x,y).

Options F and H don't multiply by the coordinates but add to them, thus they are not valid answers.

Option J actually multiplies by the factor 0.2 but since it's less than 1, it does not correspond to an enlargement.

Only option G multiplies by a factor 4/3=1.3 greater than 1.

Answer: Choice G.
