Step-by-step explanation:
y=-x+2
f(-2) = -(-2)+2
= 2+2
= 4
f(-3/2) = -(-3/2) +2
= 3/2 +2
= 7/2 or 3.5
f(-3/4) = -(-3/4) +2
= 3/4 +2
= 11/4 or 2.75
y= x^3 -2x^2 -4x +3
f(1/2) = (1/2)^3 -2(1/2)^2 -4(1/2) +3
= 1/8 -1/2 -2 +3
= 5/8
f(0) = (0)³-2(0)²-4(0)+3
= 0+0+0+3
= 3
f(-2) = (-2)³-2(-2)²-4(-2)+3
= -8-8+8+3
= -5
