Let f(x) = 2x2 + 7x - 5 and g(x) = -8x2 - 3x + 5.
what is g(x) + f(x)?

-6x^2+4x

Step-by-step explanation:

Add them

2x^2+7x-5

-8x^2-3x+5

2x^2-8x^2=-6x^2

7x-3x=4x

-5+5=0

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
