Given the functions below, find (h. g) (4).
g(x) = 3x +3
h(x) = -4x + 1

  (h·g)(4) = -225

Step-by-step explanation:

We assume your (h.g) is supposed to represent the product h(x)g(x). Filling in the numbers and doing the arithmetic, we have ...

  (h·g)(4) = h(4)·g(4) = (-4(4)+1)(3(4)+3) = (-15)(15)

  (h·g)(4) = -225

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

step-by-step explanation:

x+2> 6

subtract 2 from each side

x+2-2 > 6-2

x > 4

there is an open circle at 4 since is it is greater than and the line goes to the right
