anonymous · Answer

how can i do that cause its next to f.. do i classify f as 1 ?

anonymous · Answer

Put where x -1, 0 and 4 so you take
x= -1, y= -9
x=0, y= -7
x=4, y=1 
so Range={-9, -7, 1}

oh .

anonymous · Answer

same thing..substitute x=-1 ...find y...
x=0 find y ....x=4 find y.!!

can you help me with my next question please

anonymous · Answer

thank u rebecca

anonymous · Answer

okay msg me the url

anonymous · Answer

when x = -1 then f(-1)=3*(-1)-8=-11
when x = 0 then f0) = 3*0-8=-8
when x = 3 then f(4)= 3*4-8=4
so range = {-11,-8,4)
