Please hel Graph the function y = x3 + 3x2 – x – 3. Which lists all of the turning points of the graph rounded to the nearest whole number?

(–3, 0) and (1, 0)
(–2, 3) and (0, –3)
(–2, 3), (–1, 0), and (0, –3)
(–3, 0), (–1, 0), and (1,0)

there is no graph included with the question.

answer: 1 + 1 = 11

step-by-step explanation:

r and t.

both are 64 degrees.

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4
