Answer:
We have to determine the graph of the given inequality as:
on solving this equation we get:
Since we know that:
Now we know that when the value of:
Also for the value other than -1 the function being a quadratic function will always give a non-zero positive value.
Hence, range of the function in intervals could be written as:
(-∞,-1)∪(-1,∞).
Hence, the graph of the function will be the whole of the number line with a open circle on -1.
The question is an illustration of inequalities.
The inequality that represents Lashonda's amount of exercise is:
The given parameter is:
In inequality, at least means <em>greater than or equal to</em>.
So, the above equation becomes:
From the question, we understand that the number of minutes should be represented with t.
So, we have:
Hence, the inequality is:

Answer:
Second Option: 3, -3
Step-by-step explanation:
In the graph of the supplied function we observe f (x) is a piece wise function composed of two line segments and a point.

We must find the limit when x approaches 2 from the left
and we must find the limit when x approaches 2 on the right.
when x approaches 2 on the left then . If
then
, therefore the
When x approaches 2 on the right then . If
