there is a zero at x = 1 (option D)
Step-by-step explanation:
a) The graph shows it is going up (increasing towards both the y axis and x axis).
This graph will give a positive leading coefficient.
As a result, the equation will have a positive leading coefficient not a negative one.
b) zeros of a polynomial are the values of x when the line crossses the x axis.
From our graph, the line doesn't cross the x axis at x = 6.
As a result, there is no zero of -6.
Multiplicity tells us the number of times the number of times a factor occurs.
Since part of the statement is wrong, it makes the whole statement wrong
c) The degree of this graph is odd. Its equation is 3rd degree
d) From the graph, the line crosses the x axis at x = 1 (2nd tick line)
Each tick line represents 0.5
The zero is the value of x when it crosses the x axis
As a result the polynomial has a zero at x = 1
The correct option is there is a zero at x = 1 (option D)
