What are the domain and range of f(x) = 4x-8
1.domain: {x | x is a real number}; range: {yly> -8}
2.domain: {x 1 x is a real number}; range: {yly > 8}
3.domain: {x | x > 4}; range: {yl y> -8}
4.domain: {x|x> -4}; range: {yly > 8}

the y will be in still but your answer will be y x 3

step-by-step explanation:

jk: )

x/3-10=8

x/3=18

x=48

27

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
