Question

Will give medal!What is the resulting ordered pair if the value of the independent variable is 2?

f(x) = –5x + 4

Answer 1

if you have f(x), then the independent variable is x.
So if x = 2, what is f(x)?
\[\Large f(2) =\color{red}?\]

Answer 2

2f..?

Answer 3

You mustn't mistake f(x) as any sort of multiplication, no...
f(x) = -5x + 4
f(a) simply means you replace the x with a.
f(a) = -5a + 4

f(5) means you replace the x with 5...
f(5) = -5(5) + 4 = -25 + 4 = -21

That said, what is f(2)= ?

Answer 4

2?

Answer 5

NO... like I said, replace the x in -5x + 4 with a 2, and what do you get?

Answer 6

idk

Answer 7

\[\Large f(\color{red}x) = -5\color{red}x +4\]\[\Large f(\color{red}2) = -5(\color{red}2)+4\]
now solve :)

Answer 8

14..?

Answer 9

-14!

Answer 10

It's a +4 there, not a -4 :P
