Question

PLEASE HELP ASAP!
The functions f(x) and g(x) are defined below.

f(x) = -21x + 6
g(x) = -20x + 1

Using a table of values, determine the solution to the equation f(x) = g(x).
A. x = 5
B. x = -99
C. x = -5
D. x = 7

Answer 1

C?

Answer 2

f(x) = g(x)
which is
-99 = -99

Answer 3

try subtitute the other x to the f(x) and g(x) and see if its equal.
