## anonymous one year ago Use the functions m(x) = 5x + 4 and n(x) = 6x − 9 to complete the function operations listed below. Part A: Find (m + n)(x). Show your work. (3 points) Part B: Find (m ⋅ n)(x). Show your work. (3 points) Part C: Find m[n(x)]. Show your work. (4 points)

okay so basically what part A is saying is find m(x) + n(x) part B is saying m(x) * n(x) part C is saying plug n(x) equation for x in the m(x) equation

2. anonymous

so for part A do i just use the number for m that does not have a x in it?

3. anonymous

so basically its saying (5x+4) + (6x-9)

$$\large { (m+n)(x)\implies m(x)+n(x) \\ \quad \\ (m\cdot n)(x)\implies m(x)\cdot n(x) \\ \quad \\ m[n(x)]\implies \begin{cases} m(x) = 5x + 4\\{\color{brown}{ n(x) }} = 6x - 9 \end{cases}\qquad m[n(x)]=5[{\color{brown}{ n(x) }}]+4 }$$

idk if that answers ur quesiton

6. anonymous

i got 11x-5?

8. anonymous

omg no way so did I :D

9. anonymous

so what do i put for part A?

11. anonymous

ok now part b

12. anonymous

tell me what you get read over my first comment and try it out

13. anonymous
