13. When a linear function is graphed, it passes through the points (-1, 1), (1,5), and (3,9).
Part A: What is the rate of change for the function?
Part B: Does the equation y =
2x + 3 represent the function? Explain your reasoning.
Your answer
14.

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  

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0
