Answer:
-12
Step-by-step explanation:
What you have to do is plug -4 into the function as a puzzle. So, replace all x with -4.
f(-4) = 7(-4) - 4(-4) = -28 + 16 = -12

what is range of the inverse of the relation {(1, 7), (-2, 4), (5, 6), (2, 8)} A. {1, 2,5} B. {-4, 6, 7, 8} C. {1, 5} D. {-4, 7,

The answer should be the domain of this relation. {-2, 1, 2, 5} but I do not see that as one of your answer choices.
The inverse of a relation is when you switch the domain and range. In other words, the domain of the original relation becomes the range of the inverse.
Slope formula: y2-y1/x2-x1
Plug in: -15-0/-11-3 = -15/-14 = 15/14 = slope
