Which interval below correctly describes the range of the graph f (x)? A.) y ≤ 3
B.) - 3 ≤ y ≤ 5
C.) -5 ≤ y ≤ 3
D.) All real numbers

The dot on the graph is at (1,3) And the two lines are going down and never stop.

they can both be solutions depends on the equation

step-by-step explanation:

what is the equation? ?

< xcy ≅ < xby

step-by-step explanation:

in δcax and δbax,

so, δcax ≅ δbax (side-angle-side or sas)

since δcax ≅ δbax, we can conclude < acx ≅ < abx

in δacy and δaby,

so, δacy ≅ δaby (side-angle-side or sas)

since δacy ≅ δaby, we can conclude < acy ≅ < aby

now,

< acy ≅ < aby

=> < acx + < xcy ≅ < abx + < xby

=> < acx + < xcy ≅ < acx + < xby   (since < acx ≅ < abx already proved above)

subtracting < acx from both sides, we get

< acx + < xcy -< acx ≅ < acx + < xby -< acx

cancelling out < acx and -< acx from both sides, we get

< xcy ≅ < xby (proved)

i believe b is the answer
