What's The Question?

anonymous · Answer

Here we go! The table below shows some values of f(x) and g(x) for different values of x.


x        f(x) = 9x + 7          g(x) = 5x
-2          -11
-1          -2
0                                           1
1                                           5
2


Complete the chart and determine the solution of the equation f(x) = g(x)?
 A.) x = -1

 B.) x = 0

 C.)  x = 2

 D.) x = 25

x        f(x) = 9x + 7          g(x) = 5x
-2          -11                       0.04
-1          -2                         0.2
0              7                            1
1             16                           5
2             25                         25

I can't decide between the answers C. or D.. That's the only help I need.

anonymous · Answer

well the answer is right there f(x)=g(x) when x=2

anonymous · Answer

so, the answer is C. ?

anonymous · Answer

I'm guessing that's correct then. :)
