Q:
# What are the apparent zeros of the cubic function graphed above? (also if you have the answers to the rest of this test plz send them thx)

Accepted Solution

A:

Answer:C. {-1,2}Step-by-step explanation:We are given the graph of a cubic function.Fundamental Theorem of Algebra states that 'An n-degree function will have n number of zeroes'.Thus, the given cubic function will have 3 zeroes.Since, we see that,The graph of the function is crossing the x-axis at the point -1.So, x= -1 is a zero of the cubic function.Also, the graph of the function touches the x-axis at the point 2.So, x= 2 is also a zero of the cubic function with multiplicity 2 (i.e. they are repeating zeroes).Thus, the three zeroes of the cubic function are -1, 2 and 2.Hence, according to the options,The zeroes of the cubic function are {-1,2}.
