A company opened in 1998 and turned a profit its first year. The company's revenues increased annually thereafter. Which of the
following functions could model this situation where x represents the number of years in operation, and f(x) represents the
company's annual revenue [in millions]?

B. f(x) = 884 •

Step-by-step explanation:

I think your question missed key information, allow me to add in and hope it will fit the orginal one. Please have a look at the attached photo

My

Given that:

The following functions could model this situation is:

B. f(x) = 884 • where:

884 is a profit its first year

1.22 growth rate in revenue

x  represents the number of years in operation

Hope it will find you well.

3. parallelogram

step-by-step explanation:

we turn each of our sides into direction vectors

ab=b-a=(3 - 7, 1 - 0) = (-4, 1)

bc=c-b=(1,6)

cd=d-c=(4,-1)

da=a-d=(-1,-6)

we see how the opposite sides have negated direction vectors; this is characteristic of a parallelogram.   we have congruent sides ab=cd and bc=da with unequal lengths because 1^2+6^2 is different from (-4)^2+1^2.   so it's not a square or a rhombus.  

we check the dot product of direction vectors of adjacent sides.   we have

ab dot bc = -4(1) + 1(6) = 2

that's not zero so the sides are not perpendicular.   we've ruled out rectangle.

the direction vectors indicate two pairs of congruent parallel sides, so we choose parallelogram over trapezoid.
