Question

Given f(x) and g(x) = k-f(x), use the graph to determine the value of k.

Answer 1

(3,-2) because that the graph describes it

Answer 2

Answer:

k = -3

Step-by-step explanation:

f(x) = x + 4

g(x) = -3x - 12

Plug this in for g(x) = k*f(x)

[NOTE: the dot *  is a multiplication sign]

-3x -12 = k(x+4)        divide by x-4 on both sides

-3 = k                        we're done!
