Answer:
f(x)⁻¹ = (x - 11)²
Step-by-step explanation:
To find the inverse of the function, you need to (1) swap the places of the "x" and "y" variables and then (2) solve for "y". Remember, f(x) is another way of writing "y".
y = √x + 11 <----- Original equation
x = √y + 11 <----- Swap variables
x - 11 = √y <----- Subtract 11 from both sides
(x - 11)² = (√y)² <----- Square both sides
(x - 11)² = y <----- Simplify
Another way of writing the output of an inverse function is with f(x)⁻¹.

Step-by-step explanation:
<h3>Uber</h3>
- $5 pickup fee
- $0.25 per mile
<u>Equation</u>
<u>Cost of 5 miles:</u>
<h3>KC yellow Cab Co.</h3>
- $1.75 pickup fee
- $0.75 per mile
<u>Equation</u>
<u>Cost of 5 miles:</u>
- y = 0.75(5) + 1.75 = $5.5
Comparing the cost we see KC yellow Cab Co. is better value for a 5 mile ride.
Answer:
14. -21 over 5, 1 over 4
Step-by-step explanation:
PQ: perform the slope formula: y2-y1 divided by x2-x1
-3 - 17 divided by 1 - (-4) = -21 divided by 5
RS: 4 - 3 divided by -5 - (-9) = 1 divided by 4
