the domain of this function is going to be all of the real positive numbers except when the denominator equals 0, because you can't divide by 0, therefore:
(√x) - 2 = 0
(√x) = 2
x = 2^2
x = 4
therefore, the domain is all of positive real numbers except 4
notice, the denominator for each fraction is the same, thus the lcd is just 3.
is point slope form of equation of a line.
given points are :
(-6,4) and (2,-9) where
we have to find slope by using above points.
m= 9-4 / -)
now, take point and put the value of slope in point-slope form of equation:
y-4=5/4(x+6) is point-slope form of equation for the line that passes through the points (-6,4) and (-2,9) .
