1. find the inverse of the function. f(x)=2x+1/2
a. f^-1=2x+1/2
b. f^-1=1/2x+1/4
c. f^-1=x-1/2
d. f^-1=1/2x-1/4

2. find the value of: 8/11{3/8+4/8}6 2/7+12 divide 4
a. 9
b. 7
c. 12 68/77
d. 5

1. d. f^-1=1/2x-1/4

Step-by-step explanation:

1. The inverse of a function is the reflection across the line y=x. The inverse is found algebraically by switching y and x in the equation and solving for y.

f(x) = 2x + 1/2

x = 2y + 1/2

x - 1/2 = 2y

(x - 1/2)/2 = y

1/2x -1/4 = y

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,

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
