Consider the function f(x) = 3x and the function g, which is shown below.
VLD [36.1K]

Answer:

<em>B. The graph of g is the graph of f shifted 2 units down</em>

Step-by-step explanation:

<u>Graph of Functions</u>

We have two functions:

f(x)=3^x

g(x)=3^x-2

Since g(x)=f(x)-2 it will be represented as an identical graph as that for f(x), but vertically displaced 2 units down. Let's check it by plugging some points

f(0)=3^0=1

g(0)=3^0-2=-1

f(1)=3^1=3

g(1)=3^1-2=1

f(3)=3^3=27

g(3)=3^3-2=25

We can notice the values of g(x) are always 2 units below f(x), thus the correct answer is

B. The graph of g is the graph of f shifted 2 units down

75km/h compute in m/s
Vlad1618 [11]
75 * 1000/3600 = 20.8333333

You just need to multiply with 1000 to get m from km and divide by 3600 because you are converting hours in seconds.

Jlenok [28]

Answer:

1 Original amount: 20

<h3>(20 - 15)/20 x 100 = (5/20) x 100 = 25% decrease</h3>

2 Original amount: 30

End amount: 45

<h3>(45 - 30)/30 x 100 = (15/30) x 100 = 50% increase </h3>

3 Original amount: 625

End amount: 550

<h3>550/625 =550 ÷ 625 =0.88</h3><h3>0.88 =0.88 × 100/100 =(0.88 × 100)/100 =88/100 =88% decrease</h3>

4 Original amount: 320

End amount: 112

<h3>(112-320):320x100 =</h3><h3>100 =(112:320-1)x100 =</h3><h3>100 =35-100 = -65% decrease</h3>

5 Original amount: 165
