Chapter 4.4, Problem 7CB

To determine

To sketch: the graph of the function $y=-0.4x+8$ and to find the values used for $X_{\min },X_{\max },Y_{\min },\text{and}{Y}_{\max }$ .

Explanation of Solution

Consider function rule $y=-0.4x+8$ .

In order to graph this function rule using calculator use below steps -

1. Press the $Y=key$
2. Then enter the function rule in front of $Y_1=$
3. In order to set borders of the graph go to WINDOW key. In window type $-20$ in front of $X_{\min }=,$ 20 in front of $X_{\max }=,$ 1 in front of $X_{scl}=,$$-20$ in front of $Y_{\min }=$ , 20 in front of $Y_{\max }=$ , 1 in front of $Y_{scl}=$ , 1 in front of $X_{res}=$
4. Press the GRAPH key.
