The directions say to sketch a graph of f and find the domain and range of f.

Step 1

Graph the parabola (y = x² - 5) ONLY between the coordinatinates of -3 and 2

Note: it is equal to -3 so that will have a filled in dot and it is not equal to 2 so that will have an open dot.

x | y

-3 | 4 (remember to color in the dot!)

-2 | -1

-1 | -4

0 | -5

1 | -4

2 | -1 (remember that this is an open dot!)

Now connect the dots.

Step 2

Graph the line (y = x - 3) ONLY from 2 to infinity

Note: it is equal to 2 so that will have a filled in dot

x | y

2 | -1 (remember to color in the dot!)

3 | 0

4 | 1

5 | 2

this goes to infinity so continue the line with an arrowhead

step-by-step explanation:

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
