Quick HELP Please! I will give BRAINLIEST !!!I’m So confused

First of all, you can notice that the function is a polynomial with degree 1, i.e. a line. This makes all the work much easier:a. To plot the function, sample two points and connect them, since the graph is a line. In particular, we may sample t=0 and t=6 to draw the endpoints of the desired portion of the graph. We have[tex]\begin{array}{c|c}t&140-10t\\0&140\\6&80\end{array}[/tex]So, all you have to do is to draw the point (0,140) and (6, 80) and connect them. The line you're drawing is the graph of [tex]f(t)=140-10t[/tex]b. Since the slope is negative, this is a downward line, meaning that the maximum is the leftmost point, and the minimum is the rightmost. We just computed those values to be 140 and 80c. The domain [0,6] means that you're modelling what will happen within the first 6 hours of observation. The range [80,140] means that, as the beginning, the tornado is 140 units, and after 6 hours the distance will be 80 units
