Question

f(x)=10-3(2x-4)

Answer 1

f(x)=22-6x

Answer 2

its a line
its a function
it has a negative slope
what do you want to know?

Answer 3

f(x)=f(-3)

Answer 4

f(-3)=40

Answer 5

10-3(2x-4)=10-3(2*(-3)-4)
10-6x+12=10-3(-6-4)
-6x+22=10-3(-10)
-6x+22=10+30
-6x+22=40
-6x=40-22
-6x=18
x=-3

Answer 6

which makes since sense it is a line
lol

Answer 7

sorry is mine skipping too many steps?

Answer 8

i assumed she/he wanted me to solve for x of the equation f(x)=f(-3)
which is just simply x=-3
f(-3)=f(-3)

Answer 9

I was solving for f(-3) because if they know that it is f(-3) then they already know that x=-3

Answer 10

right!
did you want f(-3)
or did you want to know what x was?

Answer 11

you probably wanted to know what f(-3) was
if so just look at bishop's post

Answer 12

f(-3)

Answer 13

ok. so as I said its f(-3)=40

Answer 14

right?

Answer 15

right.
