Type the number of columns to the right of the \(\times\) and press ENTER again. Type the number of rows to the left of the \(\times\), press ENTER and the cursor will move to the right of the \(times\). The cursor is positioned to the left of the \(\times\).
From the EDIT menu, use the down arrow to move the cursor to select the matrix name desired from the menu, and press ENTER.Įnter the dimensions of the matrix size as rows \(\times\) columns. Use the right arrow key twice to select the EDIT menu. The screen will show the estimated coordinates of the intersection point. Use the right and left arrow keys to move the cursor along the line until it is near the point of intersection press ENTER. Next, a point on the graph of equation Y2 is highlighted showing the prompt Second curve? Press ENTER to select that function.
A point on the graph of equation Y1 is highlighted showing the prompt First curve? Press ENTER to select that function. Select 5: Intersect from the menu and press enter If the intersection of the two functions is visible in the window, continue below: Adjust the window manually or Zoom Out, as per instructions above. If the intersection of the two functions does not show in the window, adjust the graphing window to see the intersection point. Graph the functions in a window that shows the point where they intersect. Press Y= and enter the functions into Y1 and Y2, using the X,T,θ,n key to enter the variable X Press ENTER when the cursor is located at the desired center of the window, and your calculator will zoom as instructed.įinding an intersection of two lines or curves

Once we’ve guessed at an initial window, we can adjust the window as needed by trial and error. It appears that an appropriate window would have 0 ≤ y ≤ 25000, so Ymax = 25000. Ymax should be at least as large as the amount Vijay will have at the end of 10 years, but in this case should be higher because we decided to include x values up to 15. We might decide to use 0 ≤ x ≤ 15, letting Xmax = 15. We can select a higher value for x if we want we want the value x = 10 years to be more centered in the window.
The problem refers to a time period of 10 years, so Xmax should be at least 10. Vijay invests $12000 at 5% interest for 10 years, with annual compounding. Keep this at 1 it affects the quality of the drawn graph Interval for tick marks shown on the y axis Select interval for tick marks shown on the x axis Press WINDOW and input the appropriate values for Xmin, Xmax, Ymin, Ymax. Use Xscl and Yscl to specify the desired interval for the tick marks shown on each axis. We might decide to select the graphing window as 0 ≤ x ≤ 250, 0 ≤ y ≤ 6000. In this context, only non-negative values of x and y are needed the number of items produced and the production cost don’t make sense as negative numbers. The given information indicates that the x values should go up to or beyond 200 items and the y values should go up to or beyond $5500. In this example x = the number of items and y = the cost. It costs $3500 to produce 100 items and it costs $5500 to produce 200 items.
