Given the functions:
f(x) = x^2 + 5x
g(x) = 2x + 1
Find f(5) + g(6)
Solution:
In order to find f(5) + g(6), we must first, solve for each function individually.
f(5) = (5)^2 + 5(5)
f(5) = 25 + 25
f(5) = 50
g(6) = 2(6) + 1
g(6) = 12 + 1
g(6) = 13
Equate the two values in the equation f(5) + g(6).
f(5) + g(6) = 50 + 13
f(5) + g(6) = 63
Final answer:
f(5) + g(6) = 63
