The graph is concave has two curved part as follows;
- The graph is concave up between;(0, 1), and (1, 0)
- The graph is concave down between; (0, 1), and (-a, 2)
<h3>How can the direction of concavity be found?</h3>
The direction the concave part of the graph faces is given as follows;
The graph is concave up when the concave part faces up
It is concave down when the concave part faces down
From the given diagram, we have;
The graph is concave up between;
(0, 1), and (1, 0)
The graph is concave down between; (0, 1), and (-a, 2)
Where <em>a </em>is in the range; 1 < a < 2

70 millimeters are in 7 centimeters since 10 millimeters is equal to one centimeter you would multiply 7 centimeters times 10 millimeters and get 70
Nope. its y=3x-1. the y intercept is -1, so we put that at the end. And if we take 2 points on the line and use y/x, we get 3/1 or 3, and this is our slope. Also the line is going up so its not negative
