F(x)=8/x, g(x)=8/x
f(g(x)) = f(8/x)=8/<span>8/x=x,
</span>g(f(x)) =g(8/x) =8/<span>8/x=x,
so </span>f(g(x)) = g(f(x)) = x. if <span>f of x equals eight divided by x and g of x equals eight divided by x
</span>
Answer:
x is -2
u is -2
You need to expand the brackets.
The steps are shown in the picture above. Hope this helps
Answer:
Step-by-step explanation:
A) y + ? = n^2 - 16n + ? + 69
y + 64 = n^2 -16n + 64 + 69
y + 64 = (n-8)^2 + 69
y = (n-8)^2 + 5
B) vertex is (8,5) because the value of a vertex is always (h,k) from the parent vertex function:
y = a(x-h) + k
it's a minimum only because the (a) value is positive
C) axis of symmetry = 8
