If we have a polynomial written in the form:
[tex]f(x)=(x-x_1)(x-x_2)...(x-x_n)[/tex]
Then,
[tex]x_1,x_2,...,x_n[/tex]
are x values of the zeros of the polinomial. In this case:
[tex]f(x)=(x-1)(x-7)[/tex]
Thus, x = 1 and x = 7 are zeros of the function.
Since in the zeros the y coordinate is y = 0, then:
Zeros:
(1, 0)
(7, 0)
Thus, in the graph:
