Question

Diketahui f(x)=3-2x dengan domain = {-2,-1,0,1,2} range dari fungsi itu adalah

Answer 1

F(-2) = 3 - 2(-2)
f(-2) = 3 + 4
f(-2) = 7

f(-1) = 3 - 2(-1)
f(-1) = 3 + 2
f(-1) = 5

f(0) = 3 - 2(0)
f(0) = 3 - 0
f(0) = 3

f(1) = 3 - 2(1)
f(1) = 3 - 2
f(1) = 1

f(2) = 3 - 2(2)
f(2) = 3 - 4
f(2) = -1

Range = {-1,1,3,5,7}
