Use Descartes' rule of signs to help list the possibilities for the nature of the solutions for the equation. Do not solve the equation. (Select all that apply.) 9x^2 + 3x − 16 = 0
1 positive and 1 negative solution
1 positive solution and 1 nonreal complex solution
2 negative solutions
2 positive solutions
2 nonreal complex solutions

f(x) is going down by 4

step-by-step explanation:

(its either that or its going left by 4)

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 !

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)
