Step-by-step explanation:
The domain is the possible x values of a function.
Since our function is a reciprocal function, our denominator can't equal 0. Note x=0, is a vertical asymptote.
So our domain is
All Reals except 0,
or (-oo,0) U (0, oo).
The second quartile Q₂ is nothing but the Median.
This means that it median = 4.2
5z^2 + 6a is the simplified expression
in exponent form and in word form it is 10 to the 5th power
