Step-by-step explanation:
the domain is the interval or set of all valid x-values for the function.
and the range is the interval or set of all valid y-values (functional result values) for the function.
so, we can see here that the function would create results for all x in (- infinity, + infinity). that is the domain.
now, what result values (y-values) are possible ?
we see, that the smallest functional value is y = -2.
and from there all y-values up to +infinity are possible.
so, the range is [-2, +infinity).
please consider the chosen brackets. the "[" means the value is included in the function, a "(" means that that particular interval end value is excluded. anything bigger or smaller might be valid but not this one value.
and infinity is not a value. hence they are not included in such intervals.

The Correct answer is 4/10 And 2/10.
Or you can go with 1/5
According to the given information, we build the equation for the cost. After we build the equation, the equation that relates these measures is:
Cost:
0.3 kilograms of tomatoes, at 3.30 dollars per kilogram.
Thus, the cost starts at:
y kilograms of cucumbers, at x dollars per kilogram.
Considering this, the cost will now be of:
0.2 kilograms of carrots, at z dollars per kilogram:
Now, we have to consider this for the cost, so:
