Answer:
third option: (x+3) / √x+2
Step-by-step explanation:
f(x) = √x+2 g(x) = (x² + 1) / x
(g·f)(x) = g(f(x)) = ((√x+2)² + 1) / √x+2
==> (x+2+1) / √x+2
==> (x+3) / √x+2
#2 the pattern is by 5
#4 the pattern is by 7
Answer:
$4.41
Step-by-step explanation:
10+12+15+18+20=75
75/x=17
17x=75
X=4.41
Due to the u-shaped graph suggested by these data points, this would best be matched with a quadratic function.
