For a given function ƒ(x), the operation ƒ(3x) will Question 18 options: A) stretch the graph vertically by a factor of 3. B) stretch the graph horizontally by a factor of 3. C) shrink the graph vertically by a factor of 1∕3. D) shrink the graph horizontally by a factor of 1∕3.

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
