Question

Match the functions to their ranges when the domain is {1, 2}
.f(x)=3x+5
f(x)=x^2-2x-5
f(x)=(x+5)x^2
f(x)=4-x

Answer 1

{-6, ­-5}
{8, 11}
{3, 2}
{6, 28}

Answer 2

@Kitten_is_back

Answer 3

do i do it as f(-6)=3(-5)+5 ????

Answer 4

can u help PLEASE

Answer 5

do you know what DOMAIN means ?

Answer 6

i think so

Answer 7

if you put DOMAIN in given function,then the values you are obtained are RANGE of a function

Answer 8

ok??

Answer 9

so try with first function and tell me what values you are obtained

Answer 10

f(−6)=3(−6)+5

Answer 11

f(−6)=−13

Answer 12

you have to substitute DOMAIN only

Answer 13

HOW

Answer 14

like in first function,
f(1) = ? and f(2)=?

Answer 15

f(-6)=???

Answer 16

they are the options man

Answer 17

Domain is {1,2}

Answer 18

given in question

Answer 19

understood ? @dr0zier99

Answer 20

sure thanks

Answer 21

now f(1)=?
