The functions f(x)f(x), g(x)g(x), and h(x)h(x) are shown below. Select the option that represents the ordering of the functions according to their average rates of change on the interval −7≤x≤5 goes from least to greatest.

you would have to sell 24 bracelets.

84/3.5 = 24

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
