Functions are basically another way of expressing a way to get y or x or anything (mostly used for graphs) You will see functions like <em>f(x)=</em> <em>23y-5 </em>(that was made up). Basically the number in the parenthesis in front of the f is what you're finding. So the equation after the equal sign is how to find whatever is being found. So in this case, finding x can be pretty easy. By the way, when graphing this you have x as the run and y as the rise. <em />

Answer:

1) See figure attached

2)

a) d = \sqrt{(x_2 -x_1)^2 +(y_2 -y_1)^2}

And if we replace we got:

d = \sqrt{(10 -6)^2 +(15 -9)^2}= 7.211

b) V = \frac{d}{t}

And if we replace we got:

V = \frac{7.211 ft}{2 sec}=3.606 s

Step-by-step explanation:

Part 1

We can see the plot in the figure attached.

Part 2

a)

For this case we have two points (x_1 , y_1) = (6,9) , (x_2 , y_2) = (10,15)

And we want to find the distance travelled between these two points and we can use the following formula from the euclidian distance between two points:

d = \sqrt{(x_2 -x_1)^2 +(y_2 -y_1)^2}

And if we replace we got:

d = \sqrt{(10 -6)^2 +(15 -9)^2}= 7.211

b)

Since it takes two seconds in order to go from (6.9) to (10,15) we can use the definition of velocity:

V = \frac{d}{t}

And if we replace we got:

V = \frac{7.211 ft}{2 sec}=3.606 s
