Q. What could be the equation for this graph?
y = -2x+ 1x + 3
y = (x - 2)(x + 1)(x + 3)
y = (x + 2)(x - 1)(x - 3)

Q. Which standard form function matches the factored form:
y = (x + 1)(x - 3)
y = x2 + x - 3
y = x - 2
y = x2 - 2x - 2
y = x2 - 2x - 3

Q. Which standard form function matches the factored form:
y = (x + 1)(x - 1)(x + 4)
y = x3 - x2 - 4x
y = x3 + 4x2 - x - 4
y = x3 - 4x2 + x + 4
y = x3 + x2 - x - 4
