(-1,1) (6,9)
distance = root (x1-x2)²+(y1-y2)²
so root (-1-6)²+(1-9)²= root 113 or 10.6 ≈11
the answer is B. 11.18 units
(f∘g)(3) = f(g(3))
Find g(3) by substituting x=3 in g(x)
g(x)=x²-1
g(3)=3²-1
g(3)=9-1
g(3)=8
f*g(3) = f(g(3)) = f(8)
find f(8) by substituting x=8 in f(x):
f(x)=2x+3
f(8)=2(8)+3
f(8)=16+3
f(8)=19
So f∘g(3) = 19
Sorry I am wrong
It’s D because it you do it is d
