Question

If f(x) = x² + 1 and g(x) = 3x + 1, find [f(2)-g(1)]².
A. 1
B. 2
C. 9

Answer 1

5-4=1 a

Answer 2

the way you'd write this out is:

\[f(2)= (2)^{2} +1\]

and then \[g(1)=3(1) + 1\]

when you subtract g(1) from f(2), you would get \[((2)^{2}+1)-(3*(1)+1)= 5-4 = 1\]

And then, since you want to SQUARE this answer, you would get \[(1)^{2}= 1\]

Therefore, your answer is A! Good luck!
