PLEASE HELP ANSWERS ONLY

1. 13n+15

2. 12n+18

3. 18n+12

See below.

(I only answered the first one b/c the second log function doesn't really make sense, sorry!)

Step-by-step explanation:

1. f(x) = 5 ×

Plug in 5 points.

x = -2, f(x) =

x = -1, f(x) =

x = 0, f(x) = 5

x = 1, f(x) = 15

x = 2, f(x) = 45

2. Attached below.

3. Increasing

4. Domain: x = all real numbers

Range: f(x) > 0 (because the line never goes below the x-axis)
