Answer:
D
Step-by-step explanation:
- is there any number you can put for x that won't give you a number for f(x)? No, you can use any real number.

Answer:
-167.2 ft/mile
Step-by-step explanation:
The "rise" is 1298 -1776 = -478 ft. The run is given as 15,098 ft, so the slope is ...
slope = rise/run = -478/15098 ≈ -0.0316598
For 5280 feet in 1 mile, that rate of change amounts to ...
-0.0316598×5280 ft ≈ -167.2 ft . . . per mile
The function is :
y = √(x-12), x≥12
To find the inverse function, we interchange x and y, and then make y the subject again.
So interchanging x and y we have:
x = √(y-12)
Squaring both sides gives;
x² = y-12
Now making y the subject we have,
y = x² +12
x≥0.
Therefore the inverse function is;
y = x² +12, x≥0.
Hence the correct answer is C.
