When X=0, the function would be:
f(x) = 4x^3 -20x2 + 24x
0= 4x^3 -20x2 + 24x ----->divide all by x
x(4x^2 -20x + 24) =0 ------> split -20x into -12x and -8x
x(4x^2 -12x -8x + 24)
x{4x(x-3) - 8(x -3}
x(4x-8) (x-3)
x1= 0
x2= 8/4= 2
x3= 3
steve is correct!!!1//1!!
anonymous is correct^
numbers 27 and 81 have 27 as common factor which is equal to 3^3. Noting that we can put 27 before brackets write it in form 3^3 and that third root and cube will trim.
3sqrt 27x-81-5=
3sqrt 27(x-3)-5=
3sqrt 3^3(x-3)-5=
3 3sqrt x-3-5
-5 means that graph is shifted 5 to down.
-3 means it is shifted to right by -3
3 and ∛ represent scaling of graph which can be seen and tested once you draw it. It is harder to explain it with words.
