Answer:

Step-by-step explanation:
The given polynomial function is

According to the Rational Roots Theorem, the ratio of all factors of the constant term expressed over the factors of the leading coefficient.
The potential rational roots are




Step-by-step explanation:
2-×^2
t(×)=3×
(s o t )(x)=st(×)=s(t(x))=2-(3×)^2=2-9x^2
(s o t)(-7) =2-9(-7)^2=2-9(49)= 2-441= -439
Answer:
The function in the graph is y=2x-1
The slope is 2, and the y intercept is (0, -1)
