The first answer is 80, and the second answer is still 65.5. Hope this helps!
First .... the limit of the given function is NOT EQUAL to 5 (it diverges so it has no limit). There is a typo. The 14 should be positive.

The precise definition of a limit is:

Given:

⇒ 
When ε = 0.1, δ = 0.1
When ε = 0.01, δ = 0.01
Answer:
I'm not entirely sure whether is X is with 4 under the fraction or not, so I put up both graphs results.
<h3 />
First one: F(x) = -(3/4)X +6
Second graph: F(x) = -(3/4X) + 6
Whats the math you need help with?
10 - 2(7)
10 - 14 = -4
A is the answer
