What are the domain and range of the function fix) = -3 (x-5) 2 + 4?

domain of the function are x, 1, 2, 3 and range are 6x-26, - 20, - 14, - 8

Step-by-step explanation:

f (x) = 3 (x-5) 2+4

= (3x-15) 2+4

=6x-30+4

=6x-26

if the value of x is 1

f (1) = 6*1-26

=-20

if value of x is 2

f (2) = 6*2-26

=-14

if the value of x is 3

f (3) = 6*3-26

=-8
