📝 Answered - Which table represents a function? \begin{tabular}{|c|c|} \hline$x$ & $y$ \\ \hline-4 & 2 \\ \hline 3 & 5 \\ \hline 1 & 3 \\ \hline-4 & 0 \\ \hline \end{tabular}

📝 Answered - Use the IVT to determine if there is a solution to [tex]f(x)=-9[/tex] in the interval between -2 and 4. If so, find the value of [tex]c[/tex] in the interval such that [tex]f(c)=-9[/tex]. * [tex]f(x)[/tex] is continuous on [-2,4] * -9 is not between -2 and 4 so the IVT does not apply * [tex]f(x)[/tex] is continuous on [-2,4] * -9 is between [tex]f(-2)=24[/tex] and [tex]f(4)=-24[/tex] * [tex]c=1[/tex] * [tex]f(x)[/tex] is continuous on [-2,4] * -9 is between [tex]f(-2)=24[/tex] and [tex]f(4)=-24[/tex] * [tex]c=9[/tex] * [tex]f(x)[/tex] is continuous on [-2,4] * -9 is between [tex]f(-2)=24[/tex] and [tex]f(4)=-24[/tex] * [tex]c=1, c=9[/tex]

📝 Answered - A family is canoeing downstream (with the current). Their speed relative to the banks of the river averages $2.75 mi / h$. During the return trip, they paddle upstream (against the current), averaging $1.5 mi / h$ relative to the riverbank. Write and solve a system of equations to find the family's paddling speed in still water. Let s equal the families paddling speed and c represent the current. A. $s + c =2.75$ $s-c=1.5$ B. $2.75 s= c$ $1.5 s=c$ C. $s + c =2.75$ $c-s=1.5$ D. $2.75 c=s$ $1.5 c=s$
