Y 40
y = 2x

Which of the statements about the graph of the
function y = 2% are true? Check all of the boxes
that apply.
The domain is all real numbers x because the
exponent of 2 can be any real number
When the x-values increases by 1 unit, the y-
value multiplies by 2.
The y-intercept is (0, 1).
O The graph never goes below the x-axis
because powers of 2 are never negative.
0 The range is all real numbers.

DONE

the correct ones are the 1st, 3rd and 4th

the range is (0:+infinity)

and the second statemend is false because 2²=4, but 2³=8, and 8=4=4 not 2

< 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)
