Sketch a graph of the polynomial function f(x) = –x3 + 5x2 – 2x – 8. Use the graph to complete the following: f is on the interval (1/3,3).
Fill in the bland with one of these.
(positive, negative, decreasing , increasing)

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2

show us the triangle so we can answer it
