equation:
y+=+4+-+5x
the domain is: -2,+-1, 1, 3, 4
a)
y+=+4+-+5x...........plug in x+=+-2
y+=+4+-+5%28-2%29
y+=+4+%2B+10
y+=+14
b)
y+=+4+-+5x...........plug in x+=+-1
y+=+4+-+5%28-1%29
y+=+4+%2B+5
y+=+9
c)
y+=+4+-+5x...........plug in x+=+1
y+=+4+-+5%281%29
y+=+4+-+5
y+=+-1
d)
y+=+4+-+5x...........plug in x+=+3
y+=+4+-+5%283%29
y+=+4+-+15
y+=+-11
e)
y+=+4+-+5x...........plug in x+=+4
y+=+4+-+5%284%29
y+=+4+-+20
y+=+-16
