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

x = 1/2

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

Step 2: Subtract 2 from both sides.

Step 3: Divide both sides by -4.

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.

hope i !
