Can someone help me with these 3 equations

Question

3x3 - 2x2 + 3x - 1

the value of x is
x = 0
x = 1
x = -1

expected output is
y = -1.0
y = 3.0
y = -9.0

Answer 1

y = (3, -2.0, 3.0, -1.0)

Answer 2

x = 1
x = float(x)
y = 3 * x**3 - 2 * x**2 + 3 * x - 1
print("y =", y)

Look carefully the 'y' value
