For what values of x is the graph of y equals 3 divided by the quantity 6 minus x concave upward?

up

step-by-step explanation:

the orientation of the parabolas can easily be found by analysing the power of x and y and their signs. if x is squared , parabola opens up and also if its coefficient is negative it opens down. if y is squared , the parabola opens right and also if its coefficient is negative it opens left. however in order to do the above analysis our equation must be in standard form .

our parabola is

which is not standard form of any parabola . hence we square on both hand side and convert it into standard form.

hence we see that x is squared and its coefficient is non negative . there for it opens up.

11 feet 6 inches and 8 feet 6 inches

so, converting firstly the mixed fractions to improper fractions and then "adding".
