Range of f(x)=-x+5 with domain of [-3,2] in the same notation as the domain.

when x = -3,  f(x) =  -(-3) + 5 = 3+5 = 8

when x = 2, f(x) = -2 + 5 = 3

Range of f(x)  is [3, 8]  answer

It would be an open dot on 20 going to the left.

Step-by-step explanation:

1/4x + 1 < 5

-1             -1

1/4x < 5

Divide by 1/4

x < 20

Anything less than 20 can be x. It would be an open dot on 20 going to the left (anything less than 20, ex. 19, 18, 17, 0, -1, -2, etc).
