If f(x)=5x-4 and g(x)=4x+1, find (f-g)

B

Step-by-step explanation:

What this tells you is to take 4x + 1 away from 5x - 4

Givens

f(x) = 5x - 4

g(x) = 4x + 1

Formula

(f - g)(x)

Solution

(f - g)x = 5x - 4 - (4x + 1)                remove the brackets

(f - g)x = 5x - 4 - 4x - 1                 Collect like terms

(f - g)x = 5x - 4x - 4 - 1

(f - g)x = x - 5

Answer

B

the red lines denote the population of the bacteria after 35 hours. that would be 2,409.24. the y-intercept is the blue line which is 800 because that is the starting point. the equation used to make the graph is 800(1.032)^h, where h is the number of hours.
