Let f(x)=x2 -4x and g(x) =7-x find (fg)(2)

Step-by-step explanation:

f(x) = x² - 4

g(x) = 7 - x

= (fog)(2)

= x² - 4

= (7 - x)² - 4

= (7 - 2)² - 4

= 5² - 4

= 25 - 4

= 21

(fog)(2) = 21

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5

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.
