Question

If f(x) = 2x - 9, then f(3) = -3.

True
False

Answer 1

f(3)=2(3)-9 = 6- 9 = -3
so what do u think ?

Answer 2

true or false

Answer 3

f(x) means the same thin as Y

Answer 4

so what you see then is that y = -3

Answer 5

if y = -3 than you can set it up this way:

-3 = 2x - 9

Answer 6

then you just need to solve for x. Can you do that part?

Answer 7

TRUE OR FALSE!

Answer 8

hey man...that just simply is not how this site works

Answer 9

WHY NOT?

Answer 10

\[f(x) = 2x - 9\]

\[f(3) = 2*3 - 9 = -3\]

Answer 11

So True..

Answer 18

ok ok gosh

Answer 19

Its already been solved for you so I am just gonna work out the steps at this point.

-3 = 2x - 9

goal: to get the number attached to the variable by itself. to do this you must add 9 to both sides
6 = 2x

Goal: t get the variable all by itself. To do this you must divide both sides by the number glued to the variable. which is 2.

6/2 = 3
2/2 = 1

so, 3 = 1x or x = 3

Answer 20

which is shown by f(3)= -3.
