Problem 3.

Investigate with different values of p

For k > 1, k = 1, and k < 1.

First, let's examine the graph of

First, let's examine what happens when k = 1 and we change the value of p.

p = -5 is the purple graph
p = -2 is the red graph
p = 2 is the blue graph
p = 5 is the green graph

We notice that when k = 1 the graph is a parabola opening left or right. If p is positive, the graph opens to the right and if p is negative, the graph opens to the left. The greater the absolute value of p the wider the parabola.

Next, let's examine what happens when k > 1 and we change the value of p. We will set k = 5.

p = -5 is the purple graph
p = -2 is the red graph
p = 2 is the blue graph
p = 5 is the green graph

We notice that when k =5 the graph is a hyperbola with lines at the asymptotes of the hyperbola. As p gets larger, the graph moves to the right.

Next, let's examine what happens when k <1 and change the value of p. We will set k = -5.

p = -5 is the purple graph
p = -2 is the red graph
p = 2 is the blue graph
p = 5 is the green graph

We notice that when k = -5 we get the same graph as k =5. It appears the graph is the same for positive and negative values of k.

Next, we will examine the graph of

We notice that when k = -5 we get the same graph as k =5. It appears the graph is the same for positive and negative values of k.
Looking at these three graphs we notice that the graph of this equation is a mirror image of the graph of the first equation.

Next, we will examine the graph of

First, let's examine what happens when k = 1 and we change the value of p.

p = -5 is the purple graph
p = -2 is the red graph
p = 2 is the blue graph
p = 5 is the green graph

We notice that when k = 1 the graph is a parabola. If p is positive, the parabola opens up and if p is negative, the parabola opens down. The greater the absolute value of p the wider the parabola.

Next, let's examine what happens when k > 1 and we change the value of p. We will set k = 5.

p = -5 is the purple graph
p = -2 is the red graph
p = 2 is the blue graph
p = 5 is the green graph

We notice that when k =5 the graph is a hyperbola with lines at the asymptotes of the hyperbola. As p gets larger, the graph moves down.

Next, let's examine what happens when k <1 and change the value of p. We will set k = -5.

p = -5 is the purple graph
p = -2 is the red graph
p = 2 is the blue graph
p = 5 is the green graph

We notice that when k = -5 we get the same graph as k =5. It appears the graph is the same for positive and negative values of k.
Looking at these three graphs we notice that the graph of this equation is a sideways image of the graph of the second equation.

Next, we will examine the graph of

p = -2 is the red graph
p = 2 is the blue graph
p = 5 is the green graph

We notice that when k = -5 we get the same graph as k =5. It appears the graph is the same for positive and negative values of k.
Looking at these three graphs we notice that the graph of this equation is a mirror image of the graph of the third equation.
