Answer:

2.

Domain: all real values of x

Range: f(x)》-4

3.

Domain: all real values except x = 0

Range: All real values except f(x) = 0

Step-by-step explanation:

2.

Domain: all real values of x

Range: f(x)》-4

Because this is a concave up quadratic with a minimum turning point at (0,-4)

3.

Range: All real values except f(x) = 0

Since x is in the denominator, it can't be 0

For f(x) = 0, x has to be infinity

Dima020 [189]
Rst you have to find the price of everything together

2 magazines for 9.95 each and a book for 14.95

9.95 + 9.95 + 14.95 = 34.85

Next you convert the percent to a decimal

6% = 0.06

Now you put a one in the ones place

1.06

34.85 * 1.06 = 36.94

The answer is $36.94

Hope this helps!
