Which statement best describes the domain and range of p(x) = 6-* and g(x) = 6*?
p(x) and qx) have the same domain and the same range
p(x) and g(x) have the same domain but different ranges.
p(x) and g(x) have different domains but the same range,
p(x) and g(x) have different domains and different ranges.

correct answer is a

Step-by-step explanation:

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
