Below are answers to the Practice Problems in random order.
\(-\dfrac{5}{14}\) |
Yes it is a function because when using the vertical line test any vertical line that passes over the graph will only intersect one point on the graph at a timeValue |
\({2.5, 4, 8.8}\) |
Yes it is a function because when using the vertical line test any vertical line that passes over the graph will only intersect one point on the graph at a time |
Yes it is a function because when using the vertical line test any vertical line that passes over the graph will only intersect one point on the graph at a time |
\(-\dfrac{8}{3}\) |
yes, it is a solution |
Yes because each student's ID number is individual to each student and not repeated. |
No it is not a function because \(12\) is paired with \(-2\) and \(5\). |
No because the number of students is larger than the number of days of the year, so the number of the days of the year would need to be paired with more than one student.alue |
\(1\) |
Yes it is a function because every \(x\) is paired with exactly one \( y\) |
Yes, it is solution |
\begin{array}{|c|c|c|c|c|c|} \hline \textbf{x} & -1 & 0 & 2 & 3 & -5 \\ \hline \textbf{y} & 3 & 3 & 3 & 3 & 3 \\ \hline \end{array} This is a function because every \(x\)- value is paired with exactly one \(y\)- value. No \(x\)-value is paired with two different \(y\)- values. |
No it is not a function because when using the vertical line test a vertical that passes over the graph will intersect the graph at two points at the same time. |
\(-18\) |
Yes it is a function because when using the vertical line test any vertical line that passes over the graph will only intersect one point on the graph at a time |
\(0.5\) |
Yes it is a function because every \(x\) is paired with exactly one \( y\) |
\(-\Large\frac{1}{3}\) |
Yes it is a function because every \(x\) is paired with exactly one \( y\) |
Yes it is a function because when using the vertical line test any vertical line that passes over the graph will only intersect one point on the graph at a time |
No is is not a function because when using the vertical line test, a vertical will intersect two points at the same time. It will hit the points where the \(x\)- value is \(2.5\). |
\(-28\) |
\(6\) |
No it is not a function because \(-1\) is paired with \(4\) and \(5\). |
\((2, 3) ( 3, 4) ( -2, 7) (3, 1)\) - This is not a function because \(3\) is paired with \(4\) and \(1\). |
No, it is not a solution |
No it is not a function because \(-2\) is paired with \(4\) and \(2\). |
\(4\) |
One possible solution is \((2, 1)\) |
No it is not a function because when using the vertical line test a vertical that passes over the graph will intersect the graph at two points at the same time. |
