If c(x)=4x-2 and d(x)=x2+5x what is (c×d)(x)

The answer is 2x³ + 9x² - 5x

Step-by-step explanation:

c(x)=4x-2

d(x)=x²+5x

To find (c×d)(x) we multiply both functions

That's

(c×d)(x) = (4x - 2)(x² + 5x)

Expand

We get

4x³ + 20x² - 2x² - 10x

= 4x³ + 18x² - 10x

Simplify the terms

Divide all terms by 2

The final answer is

= 2x³ + 9x² - 5x

step-by-step explanation:

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
