We have the following function that is a quadratic function:
So the graph of this function is shown in the figure below. This is a <em>parabola</em> as you can see. The roots of this functions, that is, the x-intercepts are:
As you can see in the figure. This function decreases from
and increases from 
Finally, another thing we can see from the graph is that the vertex is the point:

Answer:
39. r = 13.4
40. m = 12
Step-by-step explanation:
39. Given the equation, , to solve for r, the following are the correct steps to take to arrive at the solution:
(given)
Add 0.8 to both sides of the equation (addition property of equality)
(this is where the error occurred.)
40. The correct steps to take in solving the equation, is as follows:
(given)
Multiply both sides by 3 (multiplication property of equality)
(this is where the error occurred. This is what we should have at this line/step)
(dividing both sides by -1)
