Find the range of the function for the given domain. ->
f(x)=2x-6; {-2, -1, 0, 1, 2}

What is the range?
A. {-10, -7, -6, -3, -2}
B. {-10, -7, -7, -3, -2}
C. {-11, -8, -6, -4, -1}
D. {-10, -8, -6, -4, -2}

Range = y

Domain = x

y = 2x - 6


When x = -2

y = 2(-2) -6

y = -4 - 6

y = -10


When x = - 1

y = 2(-1) - 6

y = -2 - 6

y = -8


When x = 0

y = 0 -6

y = -6


When x  = 1

y = 2(1) - 6

y = 2 -6

y = -4


When x =  2

y = 2(2) - 6

y = 4 -6

y = -2


Solution: {-10, -8, -6 , -4, -2}

Answer: D
