Answer:
you need to write the article name or a picture of the article to get a correct answer.
Step-by-step explanation:

Look at the graph picture I attached

c is the intercept, which is why the graph crosses the y-axis at +3
to find where it crosses the x-axis, we make y = 0

To remove the parentheses, you just distribute.
So, it will become 3ax + 3b^2 - 3c +2. I don't think there is any like term in this expression.
f(x) = 112 - kx
f(-3) = 112 - k(-3)
f(-3) = 112 - (-3k)
f(-3) = 112 + 3k
121 = 112 + 3k
- 112 - 112
9 = 3k
3 3
3 = k
