Answer 1

a) f(x) = (x-3)/x-1

f(-2) = (-2-3)/-2-1

f(-2) = -5/-3

f(-2) = 5/3

f(-2) = 1 2/3

f(-1) = (-1-3)/-1-1

f(-1) = -4/-2

f(-1) = 4/2

f(-1) = 2

f(0) = (0-3)/0-1

f(0) = -3/-1

f(0) = 3/1

f(0) = 3

f(3) = (3-3)/3-1

f(3) = 0/2

f(3) = 0

f(9) = (9-3)/9-1

f(9) = 6/8

f(9) = 3/4

b) f(x) = -3 ✓x+2

f(-1) = -3 ✓-1+2

f(-1) = -3 ✓1

f(0) = -3 √0+2

f(0) = -3 √2

f(2) = -3 √2+2

f(2) = -3 √4

f(2) = -3 * 2

f(2) = -6

f(6) = -3 √6+2

f(6) = -3 √8
