Please help me with the question below! Thank you

The domain is (-3,∞)

and the range is from (-∞,∞)

Step-by-step explanation:

Remember, the domain is the values on the x-axis (from left to right) while the range is all of the values on the y-axis ( top to bottom). The x-values don't start until -3 which is why that number comes first. The other values keep going indefinitely to the right which is why there's an infinity sign. The range of y values is also indefinite because there are arrows going on infinitely up and down so it would be (-∞,∞)

< 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)
