Question

If f(x) = x 2 + 1 and g(x) = 3x + 1, find [f(2)-g(1)] 2.

Answer 1

f(2) means substitute x = 2 into the equation f(x) = x 2 + 1

g(1) means substitute x = 1 into g(x) = 3x + 1 and evaluate both.

then subtract your answers f(2) - g(1)

and lastly lit looks like you need to square the the answer above to the final part

Answer 2

thankx a lot..:)
