Given the graphs of f(x) = x – 4 and g(x) = –2x – 7, what is the solution to the equation f(x) = g(x)?
1 answer:
Answer:
C) -1
Step-by-step explanation:
we have the following functions:
and
to find the solution of
what you need to do is to match the two functions:
and now we solve this equation for x.
we move the -2x to the left as a +2x, and the -4 on to the right as a +4
:
and we add the quantities on both sides:
dividing by 3:
the solution to the equation is
C) -1

Answer:
Option (B)
Step-by-step explanation:
From the graph attached,
Vertical asymptotes of the function are x = -2, 5
Horizontal asymptote is y = 0
Now we take each option,
Option (A),
F(x) =
No horizontal asymptote
Vertical asymptote : x = -2
Option (B),
F(x) =
Horizontal asymptotes : y = 0
Vertical asymptotes : x = 5, -2
Option (C),
F(x) =
Vertical asymptote : x = 0
No horizontal asymptote.
Therefore, Function given in Option (B) matches the asymptotes given in the graph.
Option (B) represents the graph.
