Question

100 POINTS
The function f(x) = 2x2 + 3 represents the rate of a boat traveling with the current in miles per hour. The function g(x) = x + 2 represents the time the boat traveled in hours. Solve (f • g)(2), and interpret the answer.

(f • g)(2) = 15, the distance in miles the boat traveled
(f • g)(2) = 15, the number of boats
(f • g)(2) = 44, the distance in miles the boat traveled
(f • g)(2) = 44, the number of boats

Answer 1

• f(x)=2x^2+3
• g(x)=x+2

$\\ \sf\longmapsto (f.g)(2)=f(2)g(2)$

$\\ \sf\longmapsto (2x^2+3)(x+2)$

$\\ \sf\longmapsto (2(2)^2+3)(2+2)$

$\\ \sf\longmapsto (2(4)+3)(4)$

$\\ \sf\longmapsto (8+3)(4)$

$\\ \sf\longmapsto 11(4)$

$\\ \sf\longmapsto 44$

• Speed×Time=Distance
