What is the sum of an 8-term geometric series if the first term is -11, the last term is 180,224, and the common ratio is -4? A.-143,231

B.-36,047

C.144,177

D.716,144

Since its the sum of a series and not a sequence I'm kind of lost

f(x) is the value of the function. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.

step-by-step explanation:

hope this !

step-by-step explanation:

what grade level is this? need to know so i can look in my old textbooks!

the answer is 21%.

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this
