Question

Suatu fungsi di definisikan f(x)=7-½x dengan x€{-2,0,2,4} .daerah hasil fungsi tsb adalah .


please bantu yahh

Answer 1

f(x)=7-½x

-2
f(x)=7-½x
f(-2)=7-½(-2)
f(-2)=7-(-1)
f(-2)=8

0
f(x)=7-½x
f(0)=7-½(0)
f(0)=7

2
f(x)=7-½x
f(2)=7-½(2)
f(2)=7-1
f(2)=6

4
f(x)=7-½x
f(4)=7-½(4)
f(4)=7-2
f(4)=5


Hp daerah hasil f(x)=7-½x {8,6,7,5}

Answer 2

f(x)  = 7 - 1/2x
f(-2) = 8

f(x) = 7 - 1/2x
f(0) = 7

f(x) = 7 - 1/2x
f(2) = 6

f(x) = 7 - 1/2x
f(4) = 5

Range = { 8 , 7 , 6 , 5 }
