Which comparison is correct for the values of f(x) and g(x) when x=−1 ?

 

Function A: f(x)=−x^2+1

Function B:

x                       g(x)

−3                         7

−1                        −4

0                           1

2                           −2

 

 

f(−1)>g(−1)

 

f(−1)

 

f(−1)=g(−1)

Plug in -1 as x into f(x). You should get \(f(-1)=0\). From the table, you know \(g(-1)=-4\). So \(f(−1)>g(−1)\) would be the correct one.
