Answer:
<h2>R = (-∞,∞)</h2>Step-by-step explanation:
The given function is
As you can notice, it's a linear function, and it's written in slope-intercept form. So, from this expression we can deduct that the slope is 42 and the y-intercept is at -100. We deduct this information, because of the form
Where is the slope and
is the y-intercept, which in this case are
and
.
An important characteristic of linear function is that they domain and range sets are always all real numbers, the function is not restricted.
Therefore, the range of the given function is
R = (-∞,∞)

The value is:
-4
<h2>Step-by-step explanation:</h2>We are asked to find the value of the ceiling function:
As we know that the ceiling function always occupy the higher value in integers.
i.e. the ceiling function act as follows:
it takes value 0 when -1< x≤0
1 when 0 < x ≤ 1
2 when 1 < x ≤2
and so on.
As we know that:
-4.6 lie between -5 and -4.
Hence, we have:
