This is the first quadrant graph of an even function. On a coordinate plane, a function has four connecting parts. The first part is a curve facing up that goes from (0, 0) to (2.5, 9). The second part is a straight line with negative slope from (2.5, 9) to (7, 7). The third part is a straight and horizontal line from (7, 7) to (9, 7). The fourth part is a curve facing down that goes from (9, 7) through (12, 4). The function is for –9 < x < –7. The function is increasing for . The point lies on the graph of the function.

The function is constant for -9<x<-7

The function is increasing for -7<x<-3

The point (-5,8) lies on the graph of the function

The function is constant for -9<x<-7

The function is increasing for -7<x<-3

The point (-5,8) lies on the graph of the function

Step-by-step explanation:

a4 - 3a2 - 1

step-by-step explanation:

step   1   :

equation at the end of step   1   :

  ((a4) -   3a2) -   1

step   2   :

trying to factor by splitting the middle term

2.1     factoring   a4-3a2-1  

the first term is,   a4   its coefficient is   1 .

the middle term is,   -3a2   its coefficient is   -3 .

the last term, "the constant", is   -1
