Suppose that f is an exponential function such that f(x) = 4 • 2^x Which answer shows that this exponential function grows by equal factors over equal intervals?

O f(4) • f(3) = f(7) • f(6)

O f(4) + f(3) = f(7) + f(6)

O f(4) divide f(3) = f(7) divide f(6)

O f(4) – f(3) = f(7) – f(6)

2 is the final ! : )

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
