(Points : 4)
{1, 2, 3, 4}
{1, 2, 3, 4, 6}
{2, 4, 6}
{2, 4}

Answer 1

set of y co-ordinates, in this case: {1,2,3,4}

Answer 2

ok :)

Answer 3

3. For the function f(x) = 2 − 3x, find f(4).
(Points : 4)
−10
−5
12
14

Answer 4

just put 4 in place of x

Answer 5

2-3*4=2-12=-10

Answer 6

i was just going to say -10

f(x) = |x| + 4
f(x) = |x| − 4
f(x) = |x + 4|
f(x) = |x − 4|
