1) 2x-1

2) 8 , 11, 11.3

Step-by-step explanation:

1) To figure out the inverse of a function , first change the F(x) to y

y =

Then switch the x and y

x =

Solve for y. Multiply by 2 both sides. Subtract 1 from both sides.

2) Use distance formula : d =

the first two are easy because the same x value. so just calculate Δy

-2 - 6 = -8 When you square it it becomes positive 64 and square root it and it becomes 8.

the next is a Δx. same method. 8-(-3) = -11 Square and square root and you get 11.

last one use the formula. substitute values of x's and y's into equation and solve for d.

46 dollars is the answer.

step-by-step explanation:

6*6 = 36,         36+10=46
