Answer:
Cubic function
Step-by-step explanation:
Expand the brackets:
Therefore this is a cubic function as it is a polynomial function of degree three.
This is also a many-to-one function such that more than one element of the domain are connected to the same element in the range. For example,
f(0) = -4 and f(3) = -4. So when x is 0 and 3, y = -4. Hence, many-to-one.
Answer: B
Begin by simplifying the given equation, so it's rearranged into standard form. Move all the terms onto one side, so they equal 0. This would result with -3x-9=0. Quadratic formula is (-b±√(b²-4ac))/(2a). Standard form follow this variable format:
+bx+c. Use the numbers that correspond with each variable to substitute them into the quadratic formula. This would be
(-(-3)±√(-3²-4(4)(-9)/2(4).
