Determine whether the two functions are inverses. f(x) = 5x+4 and g(x)=x-4/5

The two functions are inverses.
The two functions are not inverses.

The two functions are inverses.

Step-by-step explanation:

We are supposed to find whether the two functions are inverses.

To find the inverse of f(x)

y = 5x+4

y-4=5x

Replace x with y and y with x

So,

So,

So,The two functions are inverses.

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,

just sum

10 + 10 = 20
