The domain of f(x) is {-2,0,1}. If f(x) = 4x+1, what is the range?
bekas [8.4K]

The range of function is: {-7,1,5}

Step-by-step explanation:

Given function is:

f(x) = 4x+1

Also the domain:  {-2,0,1}

In order to find the range,, we have to put the domains values in the function

So,

Putting x = -2

=4(-2)+1\\= -8+1\\=-7

Putting x = 0

=4(0)+1\\= 0+1\\=1

Putting x = 1

=4(1)+1\\= 4+1\\= 5

Hence,

The range of function is: {-7,1,5}

Keywords: domain, range

Brian has $100 in his pocket. As he is walking home 1/4th of the money falls out of his wallet. Of the remaining money, he uses
emmasim [6.3K]

Answer:

$40

Step-by-step explanation:

Brian starts at $100, then loses 1/4th of the money,

100/4 = 25,

then you subtract 25 from 100, which gives you 75

With the remaining $75, he spends $15 on girl scout cookies,

75 - 15 = 60

He then has $60 remaining, but while walking home, loses 1/3 of the total amount.

60/3 = 20,

you then subtract 20 from 60, which gives you 40

Therefore, $40 is what is remaining.
