Help me please with this function notation If F(x) = 4x -2, find each of the following values
1). F(3)
2). F(-4)
3). 10 - F(1)
4). F(5) -F(0)
5). F(-2) + 6

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

or

it's undefined because anything multiplied by 0 is 0. that said, 7 days is 168 hours

that one look
