(2/3)-j
put it in parenthesis, the 2/3 to solve it correctly.
Try C but im not 100% sure though
The graph of f(x) opens upward
For the values of x < -5 the function is a line with negative slope, for the values of x > - 5 the function is a line with positive slope.
The two lines intercept in the point (-5,-2). That is the vertex of the function; a minimum value. So, all the other points are above the line y = -2.
Yes. If you can express it as a fraction (=ratio) then it is rational. 0.8 is the same as 8/10.
