Answer:
(f•g)(4) = 45
Step-by-step explanation:
f(x)=4x+1
g(x)=x^2-5
(f•g)(x) = 4(x^2 -5)+1
(f•g)(4) = 4(4^2 -5)+1
(f•g)(4) = 4(16-5)+1
(f•g)(4) = 4(11)+1
(f•g)(4) = 44 + 1
(f•g)(4) = 45
Answer:
Step-by-step explanation:
Explanation
6 sprinters are in a race. Any one of the 6 could win. None of them can win 2 medals. So the first result is 6
