Devin and Alex are having a disagreement. Alex believes that the same model can be used to represent the sum of (x2 – 5x + 1) and (2x2 + 5x + 1) and the difference of (–22 + 1) and (-4x2 - 1). Devin disagrees. Who is correct? Explain your reasoning.

step-by-step explanation:

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2

see below

step-by-step explanation:

x+2> 6

subtract 2 from each side

x+2-2 > 6-2

x > 4

there is an open circle at 4 since is it is greater than and the line goes to the right

inverse property is the answer
