Step-by-step explanation:
Here,
y= 2x
and x € (1,2,3)
now,
when x=1 , when x=2 , when x= 3
y=2x y= 2x y=2x
= 2×1 = 2×2 = 2×3
= 2 = 4 = 6
Therefore, y = (2,3,6)
A logarithmic function is a cerve so you have to draw an x-y table and find a series of points on the graph, then connect them with smooth cerve. Always remember that (1,0) is always on the cerve.
To test whether it's a factor:
-- Divide the big number by it. 81 / 6 = 13.5 .
-- If the quotient is a whole number,
then the small number is a factor
of the big number. 13.5 is not a whole number.
-- If the quotient is not a whole number,
then the small number is NOT a factor
of the big number. 6 is NOT a factor of 81 .
