(1.) decide if function f is invertible.

Lubov Fominskaja [6]

<span>a) f(n) is the number of students in your calculus class whose birthday is on the nth day of the year.

f(n) is not invertible because several different days, n, may have the same number of students, f(n). Then for one specific f(n) you cannot determine a unique n.

b) f(x) is the volume in litters of x kilograms of water at 4 degrees celsius.?

f(x) is invertible because each x gives a different f(x), then you can determine unambiguously which f(x) corresponds to each x.

-4 has a solid dot, so -4 is included in the answer.

3 also has a solid dot, so 3 is also included in the answer.

All points between the two blue dots are also part of the solution.

Answer: Choice A.

Dante is driving 638 miles to his cousin's house. his car has a 12- gallon tank and goes 22 miles for every gallon of gasoline.

Taya2010 [7]

Each tank goes for

$12 \textrm{ gallons} \times \dfrac{22 \textrm{ miles}}{\textrm{gallon}} = 264 \textrm{ miles}$

How many times he'll have to stop will be related to

$\dfrac{638 \textrm{ miles}}{264 \textrm{ miles per tank}} = \dfrac{29}{12} = 2 \frac 5{12} \textrm{ tanks}$

He started with a full tank so that means he'll have to fill up twice, once after 264 miles, once after twice that, 528 miles.
