anonymous · Answer

I have no idea how.

danjs · Answer

It says to use a computer. Look where the function has tangent lines with negative slopes...

anonymous · Answer

ok so would it be x=0 and x=1?

danjs · Answer

Those are two points that are on a decreasing part of the function.... they are loooking for the entire interval(s)

anonymous · Answer

I don't uunderstand

danjs · Answer

For instance,  the function is decreasing for x, when -0.14 < X < 1.28

anonymous · Answer

ok. I see, I see.

danjs · Answer

Is this for calculus 1 or algebra

anonymous · Answer

Thank you:) Can describe the end behavior of f(x) = 3x32 + 8x2 − 22x + 43.

describe the end behavior of f(x) = 3x32 + 8x2 − 22x + 43.

anonymous · Answer

is the answer up on the left, and down on the right?

danjs · Answer

ok, have you done the first derivative test for increasing/decreasing intervals

anonymous · Answer

No. Not yet
