What are the domain and range of the function below? A: Domain = [0, infinity)
Range= (-infinity , infinity )

B: Domain = [0, infinity)
Range = (-infinity, 4]

C: Domain = (0,4)
Range = (-infinity, infinity)

D: Domain = (-infinity, 4]
Range = [0, infinity)

Any help is greatly appreciated!!

step-by-step explanation:

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

ca = ec

cpctc makes it so that corresponding parts of the triangle you proved to be equal are equal, the other options aren't part of the part of the triangles you proved to be equal.
