g(x) = 5. So whatever f(x) or f(-1) is, g of that is going to be 5.

wth??

gf(5) = g(f(5)) = g(5+1) since f(x) = x+1 and then g(6) = 3*6 - 2 = 18 - 2 = 16

No, by itself it is not.

1 foot in the grave.

g(x) = x + 3 Then f o g (x) = f(g(x)) = f(x + 3) = sqrt[(x+3) + 2] = sqrt(x + 5)

f(x) = x - 1g(x) = (x2 - 1)/(x + 1) = (x - 1 )(x + 1)/(x + 1) = x - 1therefore, f(x) = g(x)

1 plus 1 plus 1 plus 1 equals 1 times 4. 1 times 4 equals 4. 4 minus 4 equals 0. 0

1 plus one

=b+2h+r+x+z+q+a+p+l+f+g+d

x = 75

Let f ( x ) = 3 x 5 and g ( x ) = 3 x 2 4 x
