Question 6927
{{{y=3x^2 - 5}}} and 0 < x < 5.


well the domain is xeZ, 0 < x < 5, meaning "x is an integer but only within the quoted bounds".


So, the domain is just 1, 2, 3, 4.


To find the range, but these values into the function and the answers are the range.


i shall do 1 for you, you do the rest...


x=1, {{{y=3(1)^2 - 5}}}
y = 3(1) - 5
y = 3 - 5
y = -2
