- For the following exercises, use your graphing calculator to input the linear graphs in the Y= graph menu. After graphing it, use the 2ndCALC button and 2:zero button, hit ENTER. At the lower part of the screen you will see “left bound?” and a blinking cursor on the graph of the line. Move this cursor to the left of the x-intercept, hit ENTER. Now it says “right bound?" Move the cursor to the right of the x-intercept, hit ENTER. Now it says “guess?” Move your cursor to the left somewhere in between the left and right bound near the x-intercept. Hit ENTER. At the bottom of your screen it will display the coordinates of the x-intercept or the “zero" to the y-value. Use this to find the x-intercept. Note: With linear/straight line functions the zero is not really a “guess,” but it is necessary to enter a “guess” so it will search and find the exact x-intercept between your right and left boundaries. With other types of functions (more than onex-intercept), they may be irrational numbers so “guess” is more appropriate to give it the correct limits to find a very close approximation between the left and right boundaries. 52.Y1=4x7arrow_forwardFor the following exercises, use your graphing calculator to input the linear graphs in the Y= graph menu.

After graphing it, use the 2ndCALC button and l:valuebutton, hit ENTER. At the lower part of the screen you will see x= and a blinking cursor. You may enter any number for x and it will display the yvalue for any x value you input. Use this and plug in x=0 , thus finding the y-intercept, for each of the following graphs. 50.Y1=x+52arrow_forward
- For each of the following exercises, construct a table and graph the equation by plotting at least three points. 37.2y=x+3arrow_forwardFor the following exercises, graph y=x2 on the given viewing window. Determine the corresponding range for each viewing window. Show each graph. 77. [10,10]arrow_forwardFor the following exercises, consider this scenario: The profit of a company decreased steadily over a ten-year spam.The following ordered pairs shows dollars and the number of units sold in hundreds and the profit in thousands ofover the ten-year span, (number of units sold, profit) for specific recorded years: (46,600),(48,550),(50,505),(52,540),(54,495). 35.

- For the following exercises, use the graph in Figure 3, showing the profit, y, in thousands of dollars, of a company in a given year, x, where x represents years since 1980. Draw a scatter plot for the data provided in Table 3. Then determine whether the data appears to be linearly related.arrow_forwardFor the following exercises, consider this scenario: The weight of a newborn is 7.5 pounds. The baby gained one-half pound a month for its first year. If the function W is graphed, find and interpret the x-and y-intercepts.arrow_forwardFor the following exercises, draw a scatter plot for the data provided. Does the data appear to be linearly related? For the following data, draw a scatter plot. If we wanted to know when the population would reach 15,000, would the answer involve interpolation or extrapolation? Eyeball the line, and estimate the answer.arrow_forward
