Question

1. Si: P(x) = 3x – 4
Determine: P( m – 3)
2. Si: P(x) = –3x – 1
Determine: P(m) + P(–m)
3. Si: P(x) = –8x + 5
Determine: P(2m–1)
4. Si: P(x+1) = x
Determine: P(m)
5. Si: P(x – 2) = x+3
Determine: P(2m)

Answer 1

(1) P(m-3) P= 3. (m-3) -4 ⇒ P(m-3) = 3m -9 -4 ⇒ P(m-3) = 3m-13
(2) P(m) + P(-m) = -3m-1 + (-3)(-m) -1 = -3m-1 +3m-1 = -2
(3) P(2m-1) = -8(2m-1)+5 = -16m+8+5 = -16m+13
(4) P(x+1) =x ⇒ P(x)= x-1 ⇒ P(m)= m-1
(5) x-2 = 2m ⇒  x=2m+2 ⇒ P(x-2)= 2m+2+3 = 2m+5
