all of them??

3. Nnesha

f(x) = 3x - 7 , g(x) = x2 + 3x - 4 two functions to find (f+g)(x) you should add both functions $\large\rm \color{red}{f(x)}+\color{blue}{g(x)}$$\huge\rm \color{ReD}{ 3x - 7} +\color{blue}{ x ^2 + 3x - 4}$

4. Nnesha

now combine like terms

5. Nnesha

for (f-g)(x) subtract both functions $\huge\rm \color{reD}{(3x-7)}-\color{blue}{(x^2 + 3x - 4)}$ there is negative  sign so first distribute 2nd parentheses by negative one
