Question

the tables represent the functions f(x) and g(x).

x	f(x)
-2	-3
-1	-1
0	1
1	3
2	5

x	g(x)
-2	-9
-1	-5
0	-1
1	3
2	7

which input value produces the same output value for the two functions?

• ( x = -3 )
• ( x = -1 )
• ( x = 0 )
• ( x = 1 )

Explanation:

Step1: Compare f(x) and g(x) at x=-3

$f(-3) = -5$, $g(-3) = -13$; $-5
eq -13$

Step2: Compare f(x) and g(x) at x=-1

$f(-1) = -1$, $g(-1) = -5$; $-1
eq -5$

Step3: Compare f(x) and g(x) at x=0

$f(0) = 1$, $g(0) = -1$; $1
eq -1$

Step4: Compare f(x) and g(x) at x=1

$f(1) = 3$, $g(1) = 3$; $3 = 3$

Answer:

x = 1
