1. Show that the functions f(x)= x and g(x)= x3 are inverses of each other. 2. Show that the functions fand g are inverses of each other by showing that f(g(x))= x. i. f(x)= x°- 8 and g(x)= {x- 8 3x + 5 ii. f(x)= and g(x)= 2x+ 3 1- 2x

3. Find the inverse of the functions
i. f(x)= 3x - 2 5. 3x
ii. f(x)= 2 x- 5 o é OM​

answer:

it will cost 480 dollars to refurbish the larger wood floor

step-by-step explanation:

as it's a ratio of 4 that costs 384 dollars, divide the price by the ratio

384 / 4 = 96 dollars

96 dollars per unit of the ratio

now to get the price to refurbish the larger wood floor, times the price by the units

96 * 5 = 480

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
