7.Reflect back on this scenario and each equation you created. Would any restrictions apply to the domain and range of those equations? Explain your reasoning using complete sentences. 8.Explain, using complete sentences, why it is important to understand any limitations on the domain and range.

No, it doesn't, @cupcake111. If you think about a line, it's the set of all points that follow a certain equation. So no matter what point you choose, if it's on the line, it'll work for building the line. Does that make sense to you?

ill give u some examples of the previous thing i did
anonymous
  • anonymous
write the equation of the line in standard form from one point to another. points are (1,2) and (-2,4).
anonymous
  • anonymous
write the equation of the line in point-slope form with these two points: (-2,4) and (-5,6)
anonymous
  • anonymous
write the equation of the line in slope-intercept form with these two points: (-5,6) and (-8,8)

btw that paragraph up there should be two diff questions^^

So these are both pretty much the same. This is the process: 1. Plug into the formula\[m = \frac{ y_2 - y_1 }{ x_2 - x_1 }\]2.Take the value for m and a single point and plug into \[y=mx+b\]to evaluate your y-intercept. 3. Write the formula with the slope and y-intercept. And that's it. Do you want to do an example?

You should be able to think these out. You know what domain and range are, right?

yes

in the lesson it says:

Based on the situation when graphing equations and functions, it can be necessary to note limitations of the domain and the range. These limitations are called restrictions. Looking at the airplane question above, the y variable represents the airplane’s height above the airport. It would not be realistic to have a y value that is a negative number because that would mean the airplane is below the airport, or underground. Therefore, the range on this equation can only include positive numbers. Since y cannot be negative, the smallest number it could be would be zero. Solve for x when y is zero to find the smallest, realistic value for x.

y = on-fourth x - 1 0 = one-fourth x - 1 0 + 1 = one-fourthx -1 + 1 1 = one-fourthx 4 • (1) = (one-fourthx) • 4 4 = x
anonymous
  • anonymous
The domain must have values of 4 or greater in order to keep the range values at 0 or greater.
anonymous
  • anonymous
Does that mean the plane lands 4 miles from the airport? Yes. If the pilot plots to follow this trajectory, the airplane will land 4 miles from the airport. Airplanes adjust their trajectories during the flight due to a number of real-world constraints like wind or turbulence. It would be wise for this pilot to change his trajectory before landing!

can u just help me write a few sentences for each i dont get it. do i have to work something out for this to see if there are restrictions?
