Question

Let f(x)=3 and g(x)=6x+4. Find f(x)+g(x)

Can someone please walk me through this?

Answer 1

add \[\huge\rm \color{ReD}{f(x)} +\color{blue}{g(x)}\]
f(x) =3 so replace f(x) by 3
and g(x) by 6x+4
last and f!nal step combine like terms

Answer 2

so, 3 + 6x + 4

Answer 3

yep right!

Answer 4

Answer 11

sure

Answer 12

Let f(x)=−9x+7 and g(x)=x−13. Find f(x)−g(x)

I get -10x - 6

what am i doing wrong?

Answer 13

alright okay so there is a negative sign
first step is to distribute 2nd parentheses by negative one

Answer 14

but it's not multiplication?

Answer 15

\[\huge\rm (−9x+7) -(x−13 )\]
we need to put parentheses bec of negative sign

Answer 16

so that's why first step is to distribute!

Answer 17

ohhhhh

i see i see. thank you ~
