Step-by-step explanation:
Part B: Find (m ⋅ n)(x). Show your work.
Part C: Find m[n(x)]. Show your work.
For this case we have the following functions:
For the sum of functions we have:
Substituting values:
Adding similar terms we have:
For the multiplication of functions we have:
Substituting values:
If we apply the distributive property we have:
Adding similar terms we have:
For the composition of functions we have:
Rewriting we have:
Answer: -1/3
Step-by-step explanation:
gradient = change in y/change in x
gradient = 7-8/6-3
gradient = -1/3
