What is f(x)=0
what does it equal too

x=1 at f(x)=0

Step-by-step explanation:

When graphing the function, always try to remember that f(x) is almost the same as saying 'y'. Then find the point that corresponds on the graph where y=0, which is x=1.

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
