Question

Given f(x) = x + 7 and (g)x = x - 3, what is f(x) + g(x)?

Answer 1

Hello Miss Harley :)

\[\Large\rm \color{orangered}{f(x)=x+7}\]\[\Large\rm \color{royalblue}{g(x)=x-3}\]

\[\Large\rm \color{orangered}{f(x)}+\color{royalblue}{g(x)}=\color{orangered}{x+7}+\color{royalblue}{x-3}\]

Answer 2

From there, we just need to combine like-terms.
First part make sense? We're just putting x+7 in place of f(x) and doing similar with g(x)

Answer 3

hello, thanks for helping me! yes, that does make sense! since we're combining like terms, i'd combine x and x to get 2x, right? and then combine positive 7 and negative 3 to get positive 4?

Answer 4

\[\Large\rm =2x+4\]Yayyyy good job \c:/
