determine whether each statement makes sense or does not make sense, and explain your reasoning. Show that the points \(A(1,1+d), B(3,3+d),\) and \(C(6,6+d)\) are collinear (lie along a straight line) by showing that the distance from \(A\) to \(B\) plus the distance from \(B\) to \(C\) equals the distance from \(A\) to \(C\).
How do you determine if an equation in \(x\) and \(y\) defines \(y\) as a function of \(x ?\)
If you are given a function's graph, how do you determine if the function is even, odd, or neither?
graph both equations in the same rectangular coordinate system and find all points of intersection. Then show that these ordered pairs satisfy the equations. $$ \begin{aligned} x^{2}+y^{2} &=16 \\ x-y &=4 \end{aligned} $$
determine whether each statement makes sense or does not make sense, and explain your reasoning. I graphed $$ f(x)=\left\\{\begin{array}{lll} 2 & \text { if } & x \neq 4 \\ 3 & \text { if } & x=4 \end{array}\right. $$ and one piece of my graph is a single point.
