Answer:
Explanation:
b) The number of roots, doubled tripled etc, should add up to degree. We know that the curve is even becuase both ends are facing downward.. So the roots/solutions/zeroes, should add up to an even amount.
Roots happen when the curve hits the x-axis
Root (-2,0) is a single root because it goes right through the x-axis
Root (1,0) is a triple. It does not go right through like a single, it does not bounce off (like a parabolic shape) that's a double. This tripe goes through but squiggles through so it's a triple.
C) We will use factored form and the roots. Each root goes in a parenthesis, opposite sign. If doubled will be squared, tripled will be cubed. Also there is a negative in the front because it is a negative curve.
y= -(x+2)(x-1)³
