NO LINKS TO ANWSERS!! Show your work Which formula defines the sequence f(1)=2, f(2)=6, f(3)=10, f(4)=14
A. f(1)=2, f(n)=6+f(n-1) for n>2
B. f(1)=2, f(n)=4+f(n-1) for n>2
C. f(1)=2, f(n)=2+f(n-1) for n>2
D. f(1)=6, f(n)=4+f(n-1) for n>2

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

step-by-step explanation:

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
