Question

How would I solve these type of problems?? I need help! Thanx In advance:D
Let f(x) = 3x + 2 and g(x) =x - 3. Find f(x) - g(x).

A. 4x - 1
B. 2x - 1
C. 2x + 5
D. 2x - 5

Answer 1

very easy.
according to the problem, f(x) = 3x+2 and g(x) = x - 3
you are asked to solve f(x) - g(x). Hence, just plug in the expressions of f(x) and g(x) then find its result.

Answer 2

Ok, Thought so too. I'll plug it in and show you what I got. Do you mind telling me if I got it right or wrong?

Answer 3

Sure :)

Answer 4

3x+2-x-3. \(\huge{\leftarrow}\) is that right?

Answer 5

better right it this way.
(3x+2) - (x-3)

Answer 6

*write

Answer 7

Ok, so then I would substitute. Right? I get:
3x+2-x+3. Correct?

Answer 8

Yeah.

Answer 9

My final answer is -2x+5. Am I right?

Answer 10

Wait, but I don't have that as my answer though.

Answer 11

Oh, wait. whoops. I see my mistake never mind. I got it:D Thank you soooooo much:D
